STK621-041A-E

Ordering number : EN*A0483 Thick-Film Hybrid IC STK621-041, STK621-041A-E 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. Features Integrates the 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. Use of an upper-side power supply bootstrap circuit (externally set) enables single power supply drive. Built-in ...
