Overview
The DRV8845RHHR is a quad half-bridge motor driver manufactured by Texas Instruments, designed for driving DC motors and stepper motors. It features an integrated power stage with four H-bridges capable of delivering up to 1.5 A output current per channel. The device operates within a supply voltage range of 4.5 V to 38 V and supports a wide operating temperature range from -40°C to +125°C. It utilizes a QFN-36 surface-mount package and includes protection features such as overcurrent protection and thermal shutdown.
Feature Summary
- Integrates four independent half-bridge drivers for flexible motor control configurations
- Includes built-in overcurrent protection and thermal shutdown for system reliability
- Supports multiple drive modes including full-step, half-step, and microstepping
Applications
- Printer mechanisms
- Automated vending machines
- Security systems
Procurement Notes
Verify the specific suffix RHHR corresponds to the QFN-36 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering information matches the exact electrical specifications required for your design.
Selection Notes
Select this component when a compact solution for driving multiple DC or bipolar stepper motors is required. Consider the 1.5 A continuous current rating and 38 V maximum supply voltage limits. Evaluate the thermal performance in the QFN-36 package against your application's heat dissipation capabilities.
Part Context
This part belongs to the DRV8845 family of motor drivers from Texas Instruments. It is categorized under Motor / Motion / Ignition Controllers & Drivers within the PMIC product line. The device is designed to replace discrete MOSFET solutions in space-constrained applications requiring integrated control and power stages.
Replacement Considerations
Check for pin-compatible alternatives within the DRV88xx series if different current ratings or package options are needed. Verify that any substitute maintains the same voltage and current specifications.
