DRV8832DGQR

Overview

The DRV8832DGQR is a low-voltage H-bridge motor driver manufactured by Texas Instruments. It features a dual half-bridge output configuration capable of delivering up to 1A maximum DC or RMS drive current per channel. The device operates within a supply voltage range of 2.75V to 6.8V and includes integrated power MOSFETs with a typical on-resistance of 450 milliohms for both high-side and low-side switches. It supports PWM voltage control for efficient speed regulation and incorporates thermal enhancement surface-mount packaging.

Feature Summary

• Integrated H-bridge architecture with dual half-bridge outputs for driving brushed DC motors, stepper motor windings, or other inductive loads.
• Built-in stall and lock detection mechanisms that regulate motor current during startup or obstruction events.
• Dedicated fault output pin designed to signal host processors regarding internal error conditions.
• Ultra-low power consumption with a typical standby current of 300nA in shutdown mode.

Applications

• Battery-powered consumer electronics requiring efficient motor control
• Small robotic platforms and mobile automation systems
• Vibration actuators and haptic feedback modules
• Low-power fan and pump control circuits

Procurement Notes

Verify the specific package variant against official documentation, as the DGQ suffix denotes MSOP PowerPad while the base model may utilize VSON. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for recent product change notifications regarding manufacturing site transitions or material updates. Ensure ESD handling protocols are followed due to the sensitive nature of the CMOS input structure.

Selection Notes

Select this component when designing systems operating between 2.75V and 6.8V that require precise current limiting and fault reporting capabilities. The integrated stall detection simplifies control logic compared to basic drivers lacking these features. Consider the thermal performance of the chosen package variant relative to the expected continuous current load and ambient temperature constraints.
