FEATURES
DESCRIPTION
The DRV8850 device provides a motor driver plus
LDO voltage regulator solution for consumer
products, toys, and other low-voltage or battery-
powered motion-control applications. The device has
one H-bridge driver to drive a DC motor, a voice-coil
actuator, one winding of a stepper motor, a solenoid,
or other devices. The output driver block consists of
N-channel power MOSFETs configured as an H-
bridge to drive the load. An internal charge pump
generates the needed gate-drive voltages.

2 to 5.5-V Operating Supply Voltage Range
Overvoltage and Undervoltage Lockout
Low-Power Sleep Mode
The DRV8850 device supplies up to
5 A of
continuous output current (with proper PCB heat
sinking) and up to 8-A peak current. It operates on a
supply voltage from 2.0 to 5.5 V.
100-mA Isolated Low-Dropout (LDO) Voltage
Regulator
A low-dropout linear voltage regulator is integrated
with the motor driver to supply power to
microcontrollers or other circuits. The LDO voltage
regulator can be active in device sleep mode, so that
the driver may be shut down without removing power
to any devices powered by the LDO voltage
regulator.
