General Description

Key Specifications

BV1HAL45EFJ 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.
