DRV8847SPWR

Overview

The DRV8847SPWR is a dual H-bridge motor driver manufactured by Texas Instruments, designed for bipolar stepper and brushed DC motors. It operates within a supply voltage range of 2.7 V to 18 V and delivers an output current of 2 A per channel. The device features a low operating supply 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 reliably across a temperature range of -40°C to +125°C. Packaged in a TSSOP-16 format, it integrates full control and power stages.

Feature Summary

• Integrates dual half-bridge outputs capable of driving bipolar stepper or brushed DC motors
• Includes an internal 5 V regulator for auxiliary power supply requirements
• Supports PWM input signals for precise speed and direction control
• Provides comprehensive protection mechanisms against thermal overload and overcurrent conditions

Applications

• Bipolar stepper motor control systems
• Brushed DC motor drive applications
• Small appliance motor management
• General-purpose motion control circuits

Procurement Notes

Verify the specific suffix SPWR indicates the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the datasheet revision history to validate parameter consistency for your design timeline.

Selection Notes

Select this component for designs requiring dual-channel motor actuation within an 18 V limit. The 2 A continuous current rating suits moderate load applications. Consider the TSSOP-16 footprint for space-constrained PCB layouts. Evaluate thermal dissipation requirements given the junction temperature capabilities and package size constraints.

Part Context

This part belongs to the DRV8847 family of motor drivers from Texas Instruments. It shares functional similarities with other devices in the series but differs in package type and specific electrical ratings compared to variants like the DRV8846 or DRV8833. The family targets cost-effective solutions for consumer electronics and industrial automation.
