TPS2115A

SBVS044F–MARCH2004–REVISED https://www.360docs.net/doc/d518830955.html, This integrated circuit can be damaged by ESD.Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure.Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

TTL-and CMOS-compatible input pins.Each pin has a 1-μA pull-up.Table 1illustrates the D13I functionality of D0and D1.GND 5I Ground

Primary power switch input.The IN1switch can be enabled only if the IN1supply is above IN18I the UVLO threshold and at least one supply exceeds the internal V DD UVLO.

Secondary power switch input.The IN2switch can be enabled only if the IN2supply is IN26I above the UVLO threshold and at least one supply exceeds the internal V DD UVLO.A resistor R ILIM from ILIM to GND sets the current limit I L to 250/R ILIM and 500/R ILIM for the ILIM 4I TPS2114A and TPS2115A,respectively.OUT 7O Power switch output

STAT is an open-drain output that is Hi-Z if the IN2switch is ON.STAT pulls low if the IN1STAT 1O switch is ON or if OUT is Hi-Z (i.e.,EN is equal to logic 0).
