Overview
The STK621-041 and STK621-041A-E are STK621-000 series products that use a miniature SIP package. These three-
phase 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 voltage-
level shifter circuit for upper-side device drive signal transmission, and six input signals can be input from the same voltage
potential (V SS ) 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
Features
• Air conditioner three-phase compressor motor driver.
• 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 circuit for preventing short circuits when both upper and lower inputs are ON at the same time.
• Transfer full mold structure SIP. (Single Inline Package.)
• Integrates the three-phase power main circuit, pre-driver circuit, protection circuit and level shifter circuit needed for
• IGBT and FRD used for the power main circuit devices.
• Built-in device protection circuits include an overcurrent protection circuit that detects and protects against minus bus
the inverter control circuit.
line currents with an internal shunt resistor, an thermal protection circuit, and a control supply under voltage protection
circuit. These circuits cut off the gates inside the IC and output an error signal (FAULT) when an abnormality occurs.
This prevents arm short circuits due to simultaneous upper and lower phase ON inputs.
(A dead time is needed to prevent short circuits due to switching delay.)
