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 (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 circuit for preventing short circuits when bothupper and lower
inputs are ON at the same time.
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.)
•Transfer full mold structure SIP. (Single Inline Package.)
•Integrates the three-phase powermain circuit, pre-driver circuit, protection
circuit and level shifter circuit needed for the inverter control circuit.
•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 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.
