High-voltage peripheral power driver
ALLEGRO MICROSYSTEMS
High Voltage 3 Phase Motor Drivers
Features
* Each half-bridge circuit consists of a pre-driver circuit that is completely independent from the others
* Protection against simultaneous high- and low-side turn-on (STP)
* Bootstrap diodes with series resistors for suppressing inrush current are incorporated
* CMOS compatible input (3.3 to 5 V)
* Designed to minimize simultaneous current through both high- and low-side IGBTs by optimizing gate drive resistors
* UVLO protection with auto restart
* Overcurrent protection with off-time period adjustable by an external capacitor
* Fault (FO indicator) signal output at protection activation: UVLO (low side only), OCP, and STP
* Proprietary power DIP package
Applications
* Air conditioner fan motor
* Refrigerator compressor motor
* Washing machine main motor
* Air conditioner compressor motor
