DRV8850RGYR

Overview

The DRV8850RGYR is a low-voltage half-bridge motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and delivers an output current of 5 A. The device features a built-in LDO voltage regulator and draws a typical operating supply current of 2.9 mA. Designed for surface-mount installation, it is housed in a VQFN-24 package. The component supports an extended operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a low-dropout (LDO) voltage regulator for internal circuitry support
• Configured as a half-bridge topology for brushed DC motor control
• Supports surface-mount technology via a compact VQFN-24 package

Applications

• Brushed DC motor drive circuits
• Low-voltage motion control systems
• Ignition controller interfaces

Procurement Notes

Verify the specific suffix RGYR to confirm the VQFN-24 package type and reel packaging configuration. Ensure the design accommodates the 2 V to 5.5 V supply range and 5 A current capability. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a half-bridge driver with integrated regulation is required for low-voltage applications. The 5 A output rating suits moderate load requirements. The VQFN-24 package offers thermal performance benefits for space-constrained designs compared to larger packages.

Part Context

This part belongs to the DRV88xx series of motor drivers from Texas Instruments. It complements other devices like the DRV8800RTYR, which offers full-bridge capabilities at higher voltages. The DRV8850 focuses on low-voltage efficiency and integration rather than high-voltage robustness.

Replacement Considerations

Check for direct pin-compatible alternatives within the DRV88xx family. Verify that substitute parts match the half-bridge topology and LDO integration requirements.
