Thick-Film Hybrid IC
3-phase Inverter Motor Drive
STK621-738-E
Inverter Hybrid IC
Overview
The STK621-738-E is an inverter power hybrid IC for use in 3-phase fan-motor applications and contains power stage,
pre-driver, and protection circuits.
Applications
• 3-phase inverter motor drive for air conditioners, washing machines, etc.
Features
• Protective circuits including overcurrent (bus line), and pre-drive low voltage protection are built in.
• Direct input of CMOS level control signals without an insulating circuit is possible.(Hi Active).
• Single power supply drive is possible through the use of a built-in upper-side power-supply bootstrap circuit (Needs
external capacitors).
• Built-in simultaneous upper/lower ON prevention circuit to prevent arm shorting through simultaneous ON input for
the upper and lower side transistors. (Dead time is required for preventing shorting due to switching delay.)
• The current level for overcurrent protection can be adjusted by connecting an external resistor R
between the I
SD
SD
and V terminals.
SS
• The built-in thermistor allows substrate temperature to be monitored.
