ON Semiconductor STK621-041A-E

Description
The STK621-041 and STK621-041A-E are three-phase motor driver hybrid ICs that integrate the power main circuit block and peripheral circuits needed for inverter control into a single package. They use a miniature SIP package and feature a built-in high voltage-level shifter circuit for upper-side device drive signal transmission. Six input signals can be input from the same voltage potential (VSS) as the control circuit, enabling direct connection from a control circuit such as a microcontroller without using an insulating circuit.

Features
Integrates IGBT, FRD, pre-driver, and protection circuits
Built-in thermal protection, overcurrent protection (bus line), and pre-driver supply under voltage protection
Allows CMOS-level input of control signals without an insulating circuit
Uses an upper-side power supply bootstrap circuit (externally set) for single power supply drive
Built-in circuit prevents short circuits when both upper and lower inputs are ON at the same time
Transfer full mold structure SIP (Single Inline Package)

Applications
Air conditioner three-phase compressor motor driver
