Texas Instruments DRV8935 Quad Half-Bridge Drivers

Texas Instruments DRV8935 Quad Half-Bridge Drivers are designed for driving up to four solenoid loads, two DC motors, one stepper motor, or additional loads. The output stage for each channel is comprised of N-channel power MOSFETs configured in a half-bridge. Easy interface with the controller is enabled via a simple PWM interface.

The TI DRV8935 Drivers operate off a single power supply and support a wide input supply range from 4.5V to 33V. The DRV8935 supplies up to 2.5A peak or 1.75A RMS output current per channel (dependent on PCB design). A low-power sleep mode is offered to achieve a low quiescent current draw by shutting down much of the internal circuitry.

Protection functions on the device include undervoltage-lockout, overcurrent protection on each FET, short circuit protection, and overtemperature. Fault conditions are indicated by the nFAULT pin.
