DRV8812RHDR

Overview

The DRV8812RHDR is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 28-VQFN package. It operates within a supply voltage range of 8.2 V to 45 V and supports an output current of 1.6 A. The device features four half-bridge outputs and functions as a fully integrated controller with power stages. It includes adjustable current control, overcurrent protection, and thermal shutdown. The component is designed for surface mount installation and operates between -40°C and +150°C junction temperature.

Feature Summary

Fully integrated bipolar stepper motor driver with built-in control logic and power MOSFETs
Adjustable current control mechanism allowing precise torque management
Integrated safety protections including overcurrent limiting and thermal shutdown

Applications

Bipolar stepper motor control systems
General motion control applications
Industrial automation equipment

Procurement Notes

Verify the exact part number DRV8812RHDR against official Texas Instruments documentation to ensure compatibility with your design requirements. Confirm that the 28-VQFN package dimensions and pinout match your PCB layout specifications. Check for any specific moisture sensitivity level (MSL) handling requirements during assembly. Ensure that the supply voltage and current ratings align with your motor specifications before procurement.

Selection Notes

Select this component when a compact solution for driving bipolar stepper motors is required. The integrated nature of the driver reduces external component count. Consider the thermal performance and heat dissipation capabilities of the 28-VQFN package in your system design. Verify that the operating voltage range meets your power supply constraints.

Part Context

The DRV8812RHDR belongs to the DRV8812 series of motor drivers from Texas Instruments. This series is designed for efficient and reliable control of bipolar stepper motors. The RHDR suffix indicates the specific tape and reel packaging format suitable for automated surface mount assembly processes.
