2.3.6 DRV3263-Q1

The DRV3263-Q1 is an integrated smart gate driver for 48V automotive three-phase BLDC applications. The device provides three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The DRV3263-Q1 generates the correct gate drive voltages using an external 12V supply and an integrated bootstrap diode for the high-side MOSFETs. A trickle charge pump allows for the gate drivers to support 100% PWM duty cycle control and provides overdrive gate drive voltage for driving external switches, which can be controlled through dedicated cutoff driver pins.

The DRV3263-Q1 provides low-side current sense amplifiers to support resistor based low-side current sensing. The low offset and low gain error of the amplifiers enable the system to obtain precise motor current measurements.

A wide range of diagnostics and protection features are integrated with the DRV3263-Q1, enabling a robust motor drive system design and reduce external components. The highly configurable device response allows the device to be integrated seamlessly into a variety of system designs.
