DRV8313PWPR

Overview

The DRV8313PWPR is a three half-bridge driver integrated circuit manufactured by Texas Instruments, designed primarily for driving three-phase brushless DC motors. It features independent control of each half-bridge channel using N-channel power MOSFETs. The device supports a supply voltage range of 8V to 60V and delivers up to 2.5A peak output current per channel at 24V and 25°C with adequate PCB thermal management. It includes an internal 3.3V, 10mA low-dropout regulator and provides comprehensive protection against overcurrent, short circuits, undervoltage lockout, and overtemperature conditions.

Feature Summary

• Integrates three independently controllable half-bridge drivers with N-channel power MOSFETs for efficient motor control
• Includes an internal 3.3V, 10mA low-dropout regulator to simplify external power requirements
• Provides dedicated pins for low-side current sensing on each output channel
• Features built-in protection mechanisms including overcurrent, short-circuit, undervoltage lockout, and overtemperature shutdown

Applications

• HVAC motors
• Consumer products
• Office automation equipment
• Factory automation
• Robotics technology

Procurement Notes

Verify the specific package suffix PWP corresponds to the HTSSOP-28 PowerPAD configuration required for your design. Confirm that the reel quantity matches your production needs, as this part number typically indicates tape-and-reel packaging. Ensure compatibility with your system's thermal dissipation strategy, given the surface-mount nature of the component.

Selection Notes

Select this component when designing systems requiring integrated control and power stages for three-phase BLDC motors within an 8V to 60V operating range. Consider its thermal performance in the HTSSOP-28 package if high continuous currents are expected. Evaluate the need for external current sensing versus utilizing the internal comparator functions available on the device.

Part Context

This part belongs to the DRV8313 series of motor controllers from Texas Instruments. It is functionally similar to the DRV8313PWP but differs in packaging format, with the PWPR variant supplied in reels rather than tubes. Both share identical electrical characteristics and pinouts, allowing for interchangeability based on manufacturing assembly preferences.

Replacement Considerations

The DRV8313PWP serves as a direct functional substitute with identical specifications, differing only in tube packaging instead of reel. Designers should verify that their assembly equipment supports the specific packaging type selected for production continuity.
