STK621-041 Overview
These threephase 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 voltagelevel shifter circuit for upper-side device...
