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.
