General Description

BV1HJ045EFJ-C is a 1ch high side switch for automotive

application. It has a built-in overcurrent limit function,

thermal shutdown protection function, open load

detection function, low power output-OFF function and

short-to-VCC detection function. It is equipped with

diagnostic output function for abnormality detection.
