Overview
The STK554U362A-E is an Intelligent Power Module (IPM) produced by onsemi. This highly integrated device is designed for inverter applications and contains all the high-voltage (HV) control components from HV-DC to 3-phase outputs in a single, compact SIP module. It utilizes IGBT/FRD technology and includes features such as Under Voltage Protection (UVP), Over Current Protection (OCP), and a Fault Detection output flag. The module also incorporates internal boost diodes for high-side gate boost drive and a single control power supply due to its internal bootstrap circuit.
