Description
AI
The DRV8955 provides four individually controllable 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 driver for each channel consists of N-channel power MOSFET’s configured in a half-bridge. A simple PWM (IN/IN) interface allows easy interface with the controller. Separate inputs to independently control each half-bridge are provided. Additionally, the outputs can be paralleled together to provide more current for output loads.
The DRV8955 operates off a single power supply and supports a wide input supply range from 4.5 V to 48 V. 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.
