BV1HAL85EFJ
BV1HAL85EFJ is 1ch Load Switch manufactured by ROHM.
Load Switch IC
34 V Breakdown Voltage Variable Overcurrent Detection 1ch Load Switch
General Description BV1HAL85EFJ is a single Nch MOSFET high side load switch applicable to 8.0 V to 32.0 V input. It has a built-in overcurrent protection, Thermal shutdown protection, soft-start function and low power output OFF function. It is equipped with error flag notification pin to indicate thermal shutdown and overcurrent. Single chip power supply management is possible.
