DRV8850RGYT

Overview

The DRV8850RGYT is a low-voltage H-bridge motor driver manufactured by Texas Instruments, designed for brushed DC motor control applications. It features an integrated LDO voltage regulator and operates within a supply voltage range of 2 V to 5.5 V. The device supports a continuous output current of 5 A per channel and maintains a quiescent supply current of 2.9 mA. It is housed in a VQFN-24 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates an LDO voltage regulator for simplified power management
• Supports high continuous output current capability for efficient motor driving
• Features low quiescent current consumption to enhance system efficiency

Applications

• Brushed DC motor control systems
• Motion control modules
• Ignition controller circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration distinct from other variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal design accounts for the VQFN-24 package characteristics during high-current operation.

Selection Notes

Select this component when a compact solution for low-voltage brushed DC motor actuation is required. The integrated LDO reduces external component count compared to drivers lacking on-board regulation. Evaluate the 5 A current rating against peak load requirements to ensure adequate headroom for thermal management.

Part Context

This part belongs to the DRV8850 family of low-voltage H-bridge motor drivers. It shares core functional architecture with the DRV8850RGYR variant, differing primarily in shipping and handling specifications. The series targets applications requiring precise control of small to medium-sized motors in space-constrained environments.

Replacement Considerations

The DRV8850RGYR serves as a direct alternative with identical electrical specifications but differs in reel packaging format.
