Ordering number : EN*A1033 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). • Built-in simultaneous upper/lower ON preven [ ... ]
