It provides internally fixed threshold levels with 0.1V per step ranging from 1.2V to 5V, which covers most digital applications. It features low supply current of 3μA.The RT9817 performs supervisory function by sending out a reset signal whenever the V DD voltage falls below a preset threshold level. This reset signal will last the whole period before V DD recovering. Once V DD recovered upcrossing the threshold level, the reset signal will be released after a certain delay time. To pull reset signal low manually, just pull the manual reset input (MR) below the specified V IL level. RT9817 is provided in SC-82 and SOT-143 packages.(TOP VIEW)SOT-143Marking Information For marking information, contact our sales representative directly or through a RichTek distributor located in your area, otherwise visit our website for detail.Note :Richtek p roducts are :❝RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020.❝Suitable for use in SnPb or Pb-free soldering processes.SC-82RESET/RESET MRRESET/RESET MR RT9817A = 0ms (RESET)B = 55ms (RESET)C = 220ms (RESET)D = 450ms (RESET)E = 0ms (RESET)F = 55ms (RESET)G = 220ms (RESET)H = 450ms (RESET)2DS9817-13 April 2022 Functional Block DiagramTypical Application CircuitFunctional Pin DescriptionRESET/RESETMRPart StatusThe part status values are defined as below :Active : Device is in production and is recommended for new designs.

绿色节能电流模反激 PWM 功率开关
为了滤除 MOSFET 导通瞬间 SENSE 端所产生 的瞬时大电压，防止错误的 SENCE 峰值电流 检测。在前沿消隐时间内，功率 MOSFET 始 终保持关断。这样就可以节省一个外部的 RC 网络。
内部斜波补偿
斜波补偿电路在 SENSE 端检测电压信号 上叠加了一个三角波信号。这极大的改善了系 统工作在 CCM 模式的闭环稳定性，防止次谐 波振荡，减小输出纹波电压。
