Product Introduction

Overview

The FAN73832MX_WS is a half-bridge gate-drive IC produced by onsemi, designed for driving MOSFETs and IGBTs that operate up to +600V. This IC features shutdown and programmable dead-time control functions, making it suitable for various high-voltage applications. The device utilizes onsemi’s high-voltage process and common-mode noise canceling technique to ensure stable operation under high dv/dt noise conditions. An advanced level-shift circuit allows high-side gate driver operation up to VS = -9.8V (typical) for VBS = 15V, enhancing its versatility in different configurations.
