General Description

BV2HC045EFU-C is a 2-ch high-side switch for

automotive application. It has built-in over current

protection function, thermal shutdown protection function,

open load detection function and under voltage lockout

function. It is equipped with diagnostic output function for

abnormality detection. An external component can

arbitrarily set the over current limit and the time to limit to

achieve the optimum over current protection for the load.
