DRV8850RGYT Datasheet PDF - TI

●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.

●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 V to 5.5 V.

●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.

●Internal shutdown functions provide overcurrent, short circuit, undervoltage, overvoltage, and overtemperature protection. In addition, the device also has built-in current sensing for accurate current measurement.

●The DRV8850 device is packaged in a 24-pin VQFN (3.5-mm × 5.5-mm) package (Eco-friendly: RoHS and no Sb/Br).
