DRV3256EPAPRQ1

Overview

The DRV3256EPAPRQ1 is an integrated 3-phase 48-V automotive Gate Driver Unit (GDU) manufactured by Texas Instruments. It features a 2.5-A peak sink gate drive current and operates within a supply voltage range of 5 V to 95 V and a load voltage range of 20 V to 90 V. The device is qualified to AEC-Q100 standards for automotive applications, supporting an ambient temperature grade of 0 (-40°C to +150°C). It is housed in a 64-pin HTQFP package.

Feature Summary

• Integrated three-phase gate driver architecture designed for automotive environments
• AEC-Q100 qualified with extended high-temperature operation capability up to 150°C
• High peak sink gate drive current capability for efficient motor switching

Applications

• Brushless DC (BLDC) motor control systems
• Multiphase stepper motor drives
• Automotive 48-V powertrain subsystems

Procurement Notes

Verify the complete part number including suffixes such as 'EPAPRQ1' against official Texas Instruments documentation to ensure correct package type and qualification grade. Confirm that the specific revision matches the required AEC-Q100 reliability standards for your target automotive application before finalizing procurement.

Selection Notes

Select this component when designing 48-V automotive motor control circuits requiring integrated three-phase driving capabilities. Ensure the system design accommodates the specified 5 V to 95 V supply range and utilizes the HTQFP-64 package footprint. Validate thermal management strategies to maintain junction temperatures within the -40°C to +150°C operating envelope under maximum load conditions.

Part Context

This device belongs to the DRV3256-Q1 family of integrated gate drivers from Texas Instruments. It is specifically engineered for automotive-grade reliability, distinguishing it from general-purpose industrial counterparts through its AEC-Q100 certification and extended temperature rating suitable for harsh vehicle environments.

Replacement Considerations

Consult the TI DRV3256-Q1 datasheet for officially listed pin-compatible or functionally equivalent alternatives within the same product family. Verify that any substitute maintains the required 48-V automotive qualification and 3-phase integration architecture.
