STK531U369A-E

Full Half-Bridge (H Bridge) Drivers Overview

The STK531U369A-E is a three-phase intelligent power module (IPM) inverter manufactured by onsemi. It utilizes IGBT technology and features a half-bridge output configuration with three channels. Designed for AC motor applications, it supports inductive loads and operates with a logic interface. The device handles a continuous output current of 10A per channel with a peak output capability of 20A. It withstands a maximum load voltage of 450V and requires a supply voltage between 12.5 V and 17.5 V. Operating within a junction temperature range of -40°C to 150°C, it includes status flags and fault protection mechanisms such as overcurrent limiting and under-voltage lockout. The component is housed in a 29-SIP package with molded leads.
