DRV8832DGQ

Overview

The DRV8832DGQ is a low-voltage dual H-bridge motor driver manufactured by Texas Instruments. It integrates two half-bridge drivers capable of delivering up to 1 A continuous output current per channel, with peak currents reaching 1.5 A. The device operates within a supply voltage range of 2.75 V to 6.8 V and features an ultra-low quiescent current of 1.4 mA in shutdown mode. Designed for surface-mount applications, it utilizes a 10-pin HVSSOP package with a PowerPad for thermal dissipation. The component supports a wide operating temperature range from -40°C to +85°C and includes built-in protection mechanisms such as overcurrent protection and thermal shutdown.

Feature Summary

• Integrates two independent half-bridge drivers for precise control of brushed DC motors or solenoids
• Features integrated power MOSFETs with low on-resistance for efficient energy conversion
• Includes comprehensive protection against overcurrent conditions and excessive junction temperatures
• Supports simple parallel interface control for direction and enable functions

Applications

• Battery-powered mobile robotics and autonomous vehicles
• Vibration motors and haptic feedback actuators in handheld devices
• Small fans and pump systems in consumer electronics
• Solenoid drivers in home automation and security systems

Procurement Notes

Verify the specific suffix 'DGQ' corresponds to the 10-HVSSOP package variant. Confirm end-of-life status as discontinuance notifications have been issued. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing compact systems requiring dual-channel motor control within a low voltage envelope. Consider the 1 A continuous current limit and thermal performance in the chosen package. Evaluate the need for external flyback diodes if driving inductive loads exceeding specified limits.

Part Context

This part belongs to the DRV8832 family of low-voltage motor drivers. It serves as a surface-mount alternative to through-hole variants, offering similar electrical characteristics in a smaller footprint. The DGQ designation specifically identifies the HVSSOP-10 package configuration used in space-constrained designs.

Replacement Considerations

DRV8832DGQR is a manufacturer-recommended tape-and-reel alternative.
