STK541UC62K-E
1. Product synopsis
This application handbook is intended to provide practical guidelines for the STK541UC62K-E use.
The STK541UC62K-E is Intelligent Power Module (IPM) based upon ONs Insulated Metal Substrate Tech-
nology (IMST) for 3-phase motor drives which contain the main power circuitry and the supporting con-
trol circuitry. The key functions are outlined below:
Highly integrated device containing all High Voltage (HV) control from HV-DC to 3-phase outputs in
a single small SIP module.
Output stage uses IGBT/FRD technology and implements Under Voltage Protection (UVP) and Over
Current Protection (OCP) with a Fault Detection output flag. Internal Boost diodes are provided for
high side gate boost drive.
Externally accessible embedded thermistor for substrate temperature measurement.
All control inputs and status outputs are at low voltage levels directly compatible with microcon-
trollers.
Single control power supply due to Internal bootstrap circuit for high side pre-driver circuit.
Mounting points are available on SIP package
A simplified block diagram of a motor control system is shown in Figure 1.
