The DRV8935 provides four half-bridge drivers for industrial applications. The device can be used for driving up to four solenoid loads, two DC motors, one Stepper motor, or other loads. The output stage for each channel consists of N-channel power MOSFETs configured in a half bridge. A simple PWM interface allows easy interface with the controller.
The DRV8935 operates off a single power supply and supports a wide input supply range from 4.5 V to 33 V. The DRV8935 can supply up to 2.5-A peak or 1.75-A RMS output current per channel (dependent on PCB design).
A low-power sleep mode is provided to achieve a low quiescent current draw by shutting down much of the internal circuitry. Internal protection functions are provided for undervoltage-lockout, overcurrent protection on each FET, short circuit protection, and overtemperature. Fault conditions are indicated by the nFAULT pin.
