Overview
The STK5C4U332J-E is a fully-integrated inverter power stage module produced by onsemi. This module is designed to drive permanent magnet motors and AC asynchronous motors. It features a high-voltage driver, six IGBTs (Insulated Gate Bipolar Transistors), and a thermistor, all integrated into a compact 29.6 mm x 18.2 mm dual in-line package. The module is configured in a 3-phase bridge with separate emitter connections for the lower legs, providing maximum flexibility in the choice of control algorithm. It includes a range of protection functions such as cross-conduction protection, external shutdown, and under-voltage lockout, along with adjustable over-current protection.
