1 / 23 page  Broadcom - 1 - Description The Broadcom® automotive 2.5-amp gate drive optocoupler features fast propagation delay with excellent timing skew performance. Smart features that are integrated to protect the MOSFET include desaturation sensing with shutdown protection and fault feedback, under voltage lockout and feedback, and active Miller current clamping. This full-featured and easy-to-implement gate drive optocoupler comes in a compact, surface-mountable SO-16 package for space-savings. It is ideally designed for driving power MOSFETs used in AC-DC and DC-DC converters and satisfies automotive AEC-Q100 semiconductor requirements. Broadcom R2Coupler™ isolation products provide reinforced insulation and reliability that delivers safe signal isolation critical in automotive and high temperature industrial applications.
