DRV8313RHHR

Overview

The DRV8313RHHR is a three-phase brushless DC motor driver featuring three individually controllable half-H-bridge drivers. It operates within an 8V to 60V supply voltage range and utilizes a 36-VFQFN package with exposed thermal pad. The device integrates N-channel power MOSFETs for each output channel, providing peak current capabilities suitable for driving BLDC motors or other loads like solenoids.

Feature Summary

• Integrates three independently controllable half-H-bridge drivers for precise phase control
• Features dedicated ground pins for each low-side switch to enable independent external current sensing
• Includes an internal 3.3V LDO regulator for powering peripheral logic circuits
• Provides comprehensive protection mechanisms including overcurrent, short-circuit, undervoltage lockout, and overtemperature shutdown

Applications

• Three-phase brushless DC (BLDC) motor drives
• Camera gimbal systems
• HVAC fan and pump motors
• Office automation equipment
• Robotics and factory automation actuators

Procurement Notes

Verify the specific suffix RHHR indicates tape-and-reel packaging when sourcing components. Confirm the operating temperature range and thermal requirements match the application's PCB layout constraints. Ensure compatibility with the target microcontroller logic levels and verify that the 36-pin VFQFN footprint aligns with the design schematic.

Selection Notes

Select this component for applications requiring integrated gate drive and power stages without external MOSFETs. The exposed pad design necessitates adequate copper area for thermal dissipation to maintain rated current performance. Consider the internal LDO capability if a separate 3.3V rail is unavailable in the system design.

Part Context

This part belongs to the DRV8313 family of triple half-bridge drivers from Texas Instruments. It is designed as a complete solution for driving three-phase motors, combining control logic with high-current power switches. The RHHR variant specifically denotes the reel-packaged version of the standard DRV8313 device.

Replacement Considerations

MS8313 is documented as a pin-compatible alternative offering similar functionality for HVAC and robotics applications.
