power MOSFET driver Broadcom ACPL-W346-500E optocoupler with high voltage operation and low propagation delay timing
Product Overview
The Broadcom ACPL-P346/W346 is an optically isolated power output stage designed for driving power, GaN, and SiC MOSFETs in inverter or AC-DC/DC-DC converter applications. It features an integrated circuit with a power output stage, offering high operating voltage range and high peak output current for efficient, high-frequency MOSFET driving. This optocoupler provides rail-to-rail output voltage, ensuring optimal gate voltage levels for controlled devices. With a high Common Mode Rejection (CMR) rating, it is suitable for noisy industrial environments. The input includes hysteresis for stable operation without external Schmitt triggers. The compact Stretched SO6 package facilitates smaller, more integrated designs and complies with various industrial safety standards.
