DRV8847RTET

Overview

The DRV8847RTET is a dual H-bridge motor driver manufactured by Texas Instruments, designed for controlling bipolar stepper motors and DC brushed motors. It operates within a supply voltage range of 2.7 V to 18 V and delivers an output current of 2 A per bridge. The device features a low quiescent current of 3 mA and supports PWM control interfaces with a frequency up to 400 kHz. It includes an integrated 5 V regulator and functions across an extended temperature range from -40°C to +125°C. The component is housed in a WQFN-16 surface-mount package.

Feature Summary

• Integrates two half-bridge drivers capable of driving bipolar stepper or DC brushed motors
• Includes an internal 5 V regulator for powering external logic or sensors
• Supports PWM input signals for precise speed and direction control
• Features thermal shutdown protection to safeguard against overheating

Applications

• Bipolar stepper motor control systems
• DC brushed motor drive applications
• Home appliance motor control circuits
• Industrial automation motion control modules

Procurement Notes

Verify the specific suffix RTET to confirm the WQFN-16 package type and reel packaging configuration. Ensure compatibility with the required operating voltage and current specifications for the target motor load. Check for RoHS compliance status as indicated in official documentation. Confirm availability status as distribution channels may vary for this specific part number.

Selection Notes

Select this component when a dual-channel motor solution is required within an 18 V system limit. The 2 A output capability suits moderate-load stepper and DC motor applications. The WQFN-16 package offers a compact footprint for space-constrained designs. Consider the 3 mA quiescent current for battery-operated devices requiring low standby power consumption.
