Application ReportSLUA431–December2007 bq20z75/95Printed-Circuit Board Layout Guide Doug Williams Battery ManagementABSTRACTNew single-package IC fuel gauges can significantly simplify PCB layout.Attention tolayout,however,is critical to the success of any battery management circuit board.Themixture of high-current paths with an ultralow-current microcontroller creates thepotential for design issues that can be troublesome.This document presents guidelinesthat can ensure a stable and well performing project.IntroductionNew single-package integrated circuits(IC)are available that combine the separate fuel gauge and AFE chips into one small package.This configuration can significantly simplify printed-circuit board(PCB)layout,but attention to layout is critical to the success of any battery management circuit board.Themixture of high-current paths with an ultralow-current microcontroller creates the potential for designissues.Careful placement and routing with regard to the principles described in the following discussion can ensure success.IC OrientationThe orientation of the fuel gauge IC is often driven by the shape of the board.Some pack designs have severe dimensional constraints,such as only allowing for a10-mm width.This leaves no choice but tomount the bq20z75/95IC in such a manner that no space is available for decoupling/filter capacitors to be placed next to the IC pins.In that case,adequate decoupling can be provided by mounting the capacitors on the other side of the board,as shown in Figure1.Figure1.Typical Narrow Board Design Where Most Decoupling/Filter Capacitors Are Located on OtherSide.bq20z75/95Power Supply Decoupling CapacitorFortunately,only one capacitor needs to be extremely close to the IC.The power supply decoupling from REG to VSS is very important for optimal operation of the bq20z75/95advanced gas gauge.For thebq20z95,this is the1-µF ceramic capacitor from pin32to pins31and34.Ensure that a heavy copper trace is between pins31and34.For the bq20z75,the capacitor is from REG pin26to VSS pins25and28.This is C15in the reference schematic in Figure10.SLUA431–December2007bq20z75/95Printed-Circuit Board Layout Guide1 Ground SystemTo keep the loop area small,place both terminals of this capacitor within3mm of the IC,and centered around pin32(bq20z95)or pin26(bq20z75).Use the shortest possible traces.A large loop area renders the capacitor useless and forms a little loop antenna for noise pickup.Ground SystemThe bq20z75/95requires a low-current ground system separate from the high-current PACK(–)path.Refer to the ground symbols in the bq20z75/95reference designs,and provide the separate low-current ground system accordingly.It is important that the low-current ground system only connects to PACK(–)at the sense resistor Kelvin pick-off point as shown in Figure2.The use of an optional inner layer ground plane is recommended,but not required,for the ground system.Figure2.Diagram Showing bq20z75/95Using Low-Current Ground System for Its Vss Pins andAssociated Components2SLUA431–December2007 bq20z75/95Printed-Circuit Board Layout GuideKevin Connections Kevin ConnectionsKelvin voltage sensing is extremely important in order to accurately measure current and top and bottom cell voltages.Figure3and Figure4demonstrate correct and incorrect techniques,respectively.Figure3.Incorrect Kelvin Voltage Sensing TechniqueIn Figure3,sensing through high-current copper traces produces measurement errors.SLUA431–December2007bq20z75/95Printed-Circuit Board Layout Guide3 RBI and LED CapacitorsFigure4.Correct Kelvin Voltage Sensing TechniqueAs Figure4shows,in some cases,the top and bottom cell voltage sensing may be extended out to the cells.RBI and LED CapacitorsThe3.3-V LEDOUT(pin8)output requires a4.7-µF ceramic capacitor when LEDs are used,but stillrequires2.2µF capacitance for loop stability when LEDs are not used,as with the bq20z75.Thiscapacitor also should be placed as close to the IC as is practical,but several millimeters of copper trace is not a problem.Placement of the RBI capacitor is not as critical.It can be placed further away from the IC.MRST ConnectionRESET and MRST are connected to allow the internal AFE to control the gas gauge reset state.Theconnection between these pins must be as short as possible in order to avoid any incoming noise.The recommended direct interconnection presents no problem.If unwanted resets are found,one or more of the following solutions may be effective:•Add a0.1-µF capacitor between MRST and ground.•Provide a1-kΩpullup resistor to2.5V at RESET.•Surround the entire circuit with a ground pattern.Normally,these steps are not required.If a test pin is added at MRST,provide it with a10-kΩseriesresistor.Communication Line Protection ComponentsThe5.6-V zener diodes,used to protect the communication pins of the bq20z75/95from ESD,should be located as close to the pack connector as possible.Return the grounded end of these zener diodes to the Pack(–)node,rather than to the low-current digital ground system.In this manner,ESD is diverted away from the sensitive electronics as much as possible.4SLUA431–December2007 bq20z75/95Printed-Circuit Board Layout GuideProtector FET Bypass and Pack Terminal Bypass Capacitors Protector FET Bypass and Pack Terminal Bypass CapacitorsThe general principle is to use wide copper traces to lower the inductance of the bypass capacitor circuits.In Figure5,an example layout demonstrates this technique.ing Wide Copper Traces Lowers the Inductance of Bypass Capacitors C1,C2,C3Board Offset ConsiderationsAlthough the most important component for board offset reduction is the decoupling capacitor for REG(2.5V REG),additional benefit is possible by using this recommended pattern for the Coulomb Counterdifferential low-pass filter network.Maintain the symmetrical placement pattern shown for optimum current offset e symmetrical shielded differential traces,if possible,from the sense resistor to the 100-Ωresistors as shown in Figure6.If the current sense leads are long,ensure that the100-Ωresistors are within10–15mm from the IC.Figure6.Differential Filter Components With Symmetrical LayoutSLUA431–December2007bq20z75/95Printed-Circuit Board Layout Guide5 ESD Spark GapESD Spark GapProtect SMBus Clock,Data,and other communication lines from ESD with a spark gap at the connector.The pattern shown in Figure7is recommended,with0,2-mm spacing between the points.Figure7.Recommended Spark Gap Pattern Helps Protect Communication Lines From ESDRadio Frequency InterferenceNormally,strong RF signals have no effect on gas gauge performance.However,any silicon structure can rectify RF signals,producing unwanted voltages and currents at critical nodes.In fact,any copper trace or battery connection has a frequency where it becomes an effective half-wave or quarter-wave receiving antenna.For example,the1900-MHz cell phone band has a quarter wavelength of only3,9cm.A3-watt cell phone,held next to a battery management circuit board,can induce significant errors under the right conditions.Full sweep RF testing for every new design is strongly yout modificationand/or the use of small bypass capacitors can usually mitigate the problem.The most vulnerable node on the bq20z75/95reference design is the SAFE output,which feeds into a signal diode,followed by a FET gate and shunt capacitor.This type of network demodulates an RF signal and can produce enough DC on the gate of the fuse ignition FET to actually ignite the chemical fuse.The solution is to keep the trace from the SAFE output to the diode as short as possible to reduce itseffectiveness as an antenna.Alternately,both sides of the trace can be guarded with grounded copper. Unwanted Magnetic CouplingA battery fuel gauge circuit board is a challenging environment due to the fundamental incompatibility ofhigh-current traces and ultralow-current semiconductor devices.The best way to protect against unwanted trace-to-trace coupling is with a component placement such as that shown in Figure8,where thehigh-current section is on the opposite side of the board from the electronic devices.This is not possible in many situations due to mechanical constraints;nevertheless,every attempt should be made to routehigh-current traces away from signal traces,which enter the bq20z75/95directly.IC voltage references and registers can be disturbed and,in rare cases,damaged due to magnetic and capacitive coupling from the high-current path.Note that during surge current and ESD events,thehigh-current traces appear inductive and can couple unwanted noise into sensitive nodes of the gasgauge electronics,as illustrated in Figure9.6bq20z75/95Printed-Circuit Board Layout Guide SLUA431–December2007Thermal ConsiderationsFigure8.Separating High-and Low-Current Sections Provides an Advantage in Noise ImmunityFigure9.Avoiding Close Spacing Between High-Current and Low-Level Signal LinesThermal ConsiderationsAvoid thermal problems by placing the sense resistor,protection FETS,and high-current traces well away from the ICs.SLUA431–December2007bq20z75/95Printed-Circuit Board Layout Guide7 Reference SchematicReference SchematicFigure10is a reference schematic for a4-series-cell bq20z95battery management fuel gaugeThe bq20z75schematic is similar,but has no LEDs.Figure10.bq20z954-Series-Cell Reference Schematic8bq20z75/95Printed-Circuit Board Layout Guide SLUA431–December2007IMPORTANT NOTICETexas Instruments Incorporated and its subsidiaries(TI)reserve the right to make corrections,modifications,enhancements, improvements,and other changes to its products and services at any time and to discontinue any product or service without notice.
