Overview Air Conditioner Three-Phase Compressor Motor Driver IMST Inverter Power Hybrid IC The STK621-041 and STK621-041A-E are STK621-000 series products that use a miniature SIP package. These threephase motor driver hybrid ICs integrate the power main circuit block and peripheral circuits needed for inverter control into a single package. The upper-side control power supply can be provided by a bootstrap circuit, making it possible to configure the control power supply with a single power supply (VD4 = 15V). This device also has a built-in high voltagelevel shifter circuit for upper-side device drive signal transmission, and six input signals can be input from the same voltage potential (VSS) as the control circuit. This enables direct connection from a control circuit such as a microcontroller without using a photo coupler or other insulating circuit. A basic system configuration example is shown on page 2 (Figure: Inverter System Configuration Example). Applications
• Air conditioner three-phase compressor motor driver.
