Overview

The DRV8251DDAR is a fully integrated H-bridge motor driver designed for brushed DC or bipolar stepper motors. It supports a wide operating voltage range from 4.5V to 48V and can deliver up to 4.1A of peak output current. The device features an N-channel H-bridge, charge pump regulator, and integrated current regulation to reduce external component count.

Why Choose This Part

The DRV8251DDAR offers high integration by including current sense feedback and regulation within a compact 8-pin HSOP package. Its ultra-low sleep current of 1 uA minimizes standby power consumption, while the 48V rating provides significant design margin for 24V industrial systems.

Applications

Industrial Printers
Reliable driving of paper feed motors and carriage actuators with integrated thermal and overcurrent protection.
Robotic Vacuums
Efficient control of brush and wheel motors using low-power sleep modes to extend battery life.
Smart Appliances
Driving solenoids and DC motors in coffee machines, washers, and dryers where 48V headroom is required.
Office Automation
High-voltage support for scanners and multi-function printers requiring precise PWM speed control.

Getting Started

Engineers can evaluate this driver using the DRV8251EVM evaluation module. Design involves connecting the PWM interface to a microcontroller and selecting an appropriate external shunt resistor for the integrated current regulation circuit. Ensure the PowerPad is correctly soldered to a large PCB ground plane for optimal thermal dissipation at high current loads.
