DRV8832DRCR

Overview

The DRV8832DRCR is a low-voltage motor driver manufactured by Texas Instruments, designed for battery-powered applications such as toys and printers. It integrates an H-bridge driver capable of controlling a DC motor or one winding of a stepper motor. The device operates within a supply voltage range of 2.75 V to 6.8 V and delivers up to 1 A of continuous output current when adequate PCB thermal dissipation is provided. It features PWM voltage regulation to maintain constant motor speed during battery discharge. Key electrical parameters include a maximum operating temperature of +85°C (junction up to +150°C), a quiescent current of 1.4 mA, and an on-resistance of 450 mOhms. The component is housed in a compact 3 mm × 3 mm 10-pin VSON package.

Feature Summary

• Integrates an H-bridge configuration using N-channel and P-channel power MOSFETs to drive DC motors, stepper motor windings, and solenoids.
• Includes built-in protection mechanisms such as overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature shutdown.
• Features stall/lock detection capabilities with a dedicated fault output pin to signal the host processor during motor stalling conditions.
• Supports PWM voltage regulation via input pins to optimize motor speed consistency and extend battery life in varying voltage environments.

Applications

• Battery-powered toy vehicles and accessories
• Printer motion control systems
• Low-voltage robotic actuators
• Solenoid driving circuits

Procurement Notes

Verify the specific suffix DRCR corresponds to the 10-pin VSON package and tape-and-reel packaging format. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the design accounts for thermal requirements to sustain the 1 A output rating. Check for any recent product change notifications regarding material composition or manufacturing site changes.

Selection Notes

Select this component for applications requiring a single H-bridge solution with integrated protection features. It is suitable for designs needing PWM speed control and stall detection without external discrete components. Consider the 1 A current limit and thermal performance constraints when sizing the PCB copper area. Verify that the 2.75 V to 6.8 V supply range aligns with the system's battery architecture.

Part Context

The DRV8832DRCR belongs to the DRV8832 family of low-voltage motor drivers from Texas Instruments. This series provides integrated solutions for small motor control tasks. The DRCR variant specifically denotes the VSON package option, distinguishing it from other package types like MSOP PowerPAD available in the same family. It serves as a compact alternative to discrete MOSFET implementations for space-constrained designs.

Replacement Considerations

Consult official datasheets for direct pin-to-pin replacements within the DRV8832 family. Verify compatibility of interface signals and thermal characteristics when substituting with similar H-bridge drivers from other manufacturers.
