ACFL-3161T Datasheet | Broadcom

Description The Broad® ACFL-3161T driver is a 10A peak, rail-to-rail output automotive R2Coupler™ gate drive optocoupler. The ACFL-3161T es in a pact, surface-mountable SO-12 package for space savings. It provides an isolation voltage of 5k Vrms between input and output channels. The ACFL-3161T is primarily designed with high peak driving current capability to ensure optimum performance for direct driving Si C MOSFET or IGBT in various applications. The ACFL-3161T features fast propagation delay and tight dead time distortion, which make it ideal for driving Si C MOSFET and IGBTs at high frequency DC-DC and AC-DC converters. Broad R2Coupler isolation products provide reinforced insulation and reliability that delivers safe signal isolation critical in automotive and high temperature industrial applications.
