Broadcom 5A Gate Drive - ACPL-352J with noise immunity

This 5A gate drive optocoupler is a device with integrated fail-safe IGBT and MOSFET diagnostics, protection and fault reporting. These features have become an integral part of ensuring system reliability and high availability. The device also features common mode transient immunity (CMTI) greater than 50 kV/μs and provides minimal propagation delay with excellent timing skew - this enables high frequency switching to improve efficiency in driving IGBT and SiC/GaN MOSFETs. The high peak output current and wide operating voltage range eliminate the need of an output buffer circuit.
