Thick-Film Hybrid IC
STK621-140B-E
Overview
3-phase Inverter Motor Drive
Inverter Hybrid IC
The STK621-140B-E is 3-phase inverter power hybrid IC containing power elements, pre-driver, and excessive temperature protection circuit.
Applications
• 3-phase inverter motor drive.
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. • The temperature monitor is enabled through the use of an internal thermistor. • Single power supply drive is possible through the use of a built-in upper-side power-supply bootstrap circuit (capacitor is externally connected).
