STK544UC63K-E

Overview

The STK544UC63K-E is a three-phase intelligent power module (IPM) manufactured by onsemi, designed for inverter applications. It integrates the output stage of a three-phase inverter, pre-driver circuits, bootstrap circuits, and protection mechanisms within a single SIP-23 package. The device utilizes silicon IGBT technology and supports through-hole mounting. Key electrical ratings include a collector-emitter maximum voltage of 600 V and a continuous output current capability of 10 A at standard conditions, with a peak pulse current of 20 A. The module operates within a temperature range of -40°C to +100°C and features a power dissipation rating of 22 W.

Feature Summary

• Integrates three-phase inverter output stages, pre-drivers, and bootstrap circuits into a compact SIP-23 package.
• Accepts direct CMOS level control signals without requiring external insulation circuits.
• Includes built-in overcurrent protection and under-voltage lockout for the pre-driver.
• Features internal dead-time generation to prevent shoot-through currents.
• Provides external access to lower leg emitter lines for real-time current sensing via external resistors.

Applications

• Three-phase motor drive systems
• Inverter circuits for AC motors
• Industrial automation equipment

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official datasheet to confirm compliance with RoHS directives and material declarations. Confirm that the SIP-23 package dimensions match the target PCB footprint requirements. Ensure thermal management solutions are adequate for the specified 22 W power dissipation and operating temperature limits.

Selection Notes

Select this component when a highly integrated solution for three-phase inversion is required to minimize board space and design complexity. The ability to accept direct CMOS inputs simplifies interface logic. Verify that the 600 V voltage rating and 10 A current capacity align with the load requirements. Consider the thermal resistance and heat sinking needs associated with the SIP-23 package for reliable operation.
