DRV8312DDW

Full Half-Bridge (H Bridge) Drivers Overview

The DRV8312DDW is a high-performance, integrated three-phase motor driver from Texas Instruments. It features low RDS(on) power MOSFETs and intelligent gate drive design, achieving efficiency up to 97%. The device operates with two power supplies: 12V for GVDD/VDD and up to 50V for PVDD. It supports switching frequencies up to 500 kHz while maintaining precise control. Key electrical parameters include a continuous phase current of 3.5A and a peak output current of 6.5A. The typical RDS(on) is 80mΩ for both low-side and high-side MOSFETs at TJ=40°C. The load voltage range is 0V to 52.5V.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix DDW indicates the 44-HTSSOP package with downward-facing power pads. Confirm RoHS compliance status matches project requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the target environment. Check for any recent Product Change Notifications regarding assembly or sourcing changes.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a compact solution for three-phase BLDC drives is required. The 3.5A continuous current rating suits moderate power applications. The 44-pin HTSSOP package offers a balance between thermal performance and board space. Consider the DRV8332 if higher current capacity or upward-facing power pads are needed.

Full Half-Bridge (H Bridge) Drivers Part Context

The DRV8312 belongs to the DRV83x2 family of three-phase PWM motor drivers. This series is designed for energy-efficient applications by minimizing power loss through low on-resistance MOSFETs. The family includes variants like the DRV8332, which offers higher current ratings in different packages such as QFN and HSSOP.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

The DRV8312DDWR is the reel-pack equivalent of the tube-packed DRV8312DDW. For higher current needs, consider the DRV8332 series. Verify pinout compatibility before substituting with other three-phase drivers from different manufacturers.
