IPD Series
Automotive 2ch 70 mΩ High-Side Switch
with Variable OCD and OCD Mask Function
BV2HD070EFU-C
General Description
BV2HD070EFU-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.
