3 Description
The DRV3220-Q1 bridge driver is dedicated to
automotive three-phase brushless DC motor control
applications. The device provides six dedicated
drivers for standard-level N-channel MOSFET
transistors. A boost converter with an integrated FET
provides the overdrive voltage, allowing full control on
the power stages even for low battery voltage down
to 4.75 V. The strong driver strength is suitable for
high-current applications and programmable to limit
peak output current.
PWM Frequency up to 20 kHz
Supports 100% Duty Cycle Operation
