DRV8313PWP

Overview

The DRV8313PWP is a triple half-bridge driver integrated circuit manufactured by Texas Instruments, designed primarily for driving three-phase brushless DC motors. It features three independently controllable half-bridge drivers, each utilizing N-channel power MOSFETs. The device supports a supply voltage range of 8 V to 60 V and delivers up to 2.5 A peak drive current per channel at 24 V and 25°C with adequate PCB thermal management. It includes an internal 3.3 V, 10 mA low-dropout regulator and offers comprehensive protection mechanisms such as overcurrent, short-circuit, undervoltage lockout, and overtemperature shutdown.

• Provides built-in protection against overcurrent, short circuits, undervoltage, and overheating

Applications

• HVAC motors
• Consumer electronics
• Office automation equipment
• Factory automation systems
• Robotics technology

Procurement Notes

Verify the specific package suffix PWP corresponds to the HTSSOP-28 tube configuration when sourcing. Confirm moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the ordering part number matches the exact revision and packaging quantity needed for production. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or pin assignments before finalizing procurement.

Selection Notes

Select this component for applications requiring high integration in three-phase motor control where space is limited. The integrated MOSFETs reduce external component count compared to discrete solutions. Consider the thermal performance of the PowerPAD package for high-current operations. Verify that the 8 V to 60 V input range aligns with your system's power supply architecture. Evaluate the need for external current sensing resistors given the dedicated sense pins.

Part Context

The DRV8313PWP belongs to the DRV8313 series of motor controllers from Texas Instruments. This series focuses on providing complete drive solutions for BLDC motors in compact packages. The PWP suffix denotes the 28-pin Heat-sink Thin Shrink Small Outline Package (HTSSOP) with a PowerPAD for enhanced thermal dissipation. It is part of TI's broader portfolio of power management and motion control ICs.

Replacement Considerations

The MS8313 is documented as a functional replacement with pin-to-pin compatibility. Verify electrical specifications and thermal characteristics match your design requirements before substitution.
