Automotive grade 2.5 Amp Gate Drive Optocoupler Broadcom ACPL-32JT-500E with integrated flyback controller
Product Overview
The ACPL-32JT is an automotive-grade 2.5 Amp Gate Drive Optocoupler featuring an integrated flyback controller for isolated DC-DC converters. It offers IGBT desaturation sensing with fault feedback, Under-Voltage Lock-Out (UVLO) protection with soft-shutdown and feedback, and active Miller current clamping. Designed for high noise immunity and fast propagation delay, this optocoupler enables precise timing control and efficiency in demanding automotive applications. Its compact SO-16 package with enhanced clearance and creepage makes it suitable for space-constrained designs in HEV and EV powertrains, power converters, and motor drives.
