DRV8306HRSMT

Overview

The DRV8306HRSMT is a brushless DC motor controller from Texas Instruments, designed for sensored trapezoidal control applications. It features a half-bridge output configuration with three outputs and supports a supply voltage range of 6 V to 38 V. The device utilizes power MOSFET technology and operates within a temperature range of -40°C to +125°C. It is housed in a 32-VQFN package (4x4 mm) and draws a typical operating supply current of 5 mA.

Feature Summary

• Integrated hardware-based commutation and direction management for simplified system design
• Supports sensored trapezoidal control algorithms for precise BLDC motor operation
• Built-in power MOSFET half-bridge drivers for efficient phase control

Applications

• Sensored BLDC motor control systems
• Trapezoidal commutation applications
• General-purpose motion control devices

Procurement Notes

Verify the specific suffix 'M' indicates cut-tape packaging versus 'R' for reel packaging when ordering. Confirm RoHS compliance status through official datasheets. Ensure the 32-VQFN footprint matches the target PCB layout. Validate that the 6V to 38V supply range aligns with the system power architecture.

Selection Notes

Select this component for applications requiring integrated sensored trapezoidal control without external microcontroller complexity. The 32-VQFN package suits space-constrained designs. Consider the 5 mA quiescent current for low-power requirements. Verify compatibility with the intended motor's voltage and current specifications against the 38V max limit.

Part Context

This part belongs to the DRV8306 series of brushless DC motor controllers. It shares core functional characteristics with the DRV8306HRSMR, differing primarily in packaging format. The series targets simple, cost-effective solutions for sensored BLDC motors using trapezoidal commutation strategies.

Replacement Considerations

DRV8306HRSMR serves as a direct alternative with identical electrical specifications but differs in reel packaging.
