DRV3256PEPAPRQ1

Overview

The DRV3256PEPAPRQ1 is a three-phase BLDC motor driver IC designed for automotive applications, featuring integrated high-side and low-side N-channel power MOSFETs. It supports supply voltages from 4.5V to 28V and delivers up to 3A continuous current per phase with peak currents reaching 7A. The device operates within an extended temperature range of -40°C to +150°C and includes built-in protection mechanisms such as overcurrent, overtemperature, undervoltage lockout, and short-circuit protection.

Feature Summary

• Integrated three-phase gate driver with embedded power MOSFETs
• Supports PWM, sinusoidal, and trapezoidal commutation modes
• Built-in diagnostic features including fault reporting and thermal shutdown

Applications

• Automotive cooling fan motors
• Electric power steering systems
• Throttle body actuators

Procurement Notes

Verify the specific suffix 'PRQ1' confirms automotive qualification and tape-and-reel packaging. Confirm RoHS compliance status and functional safety integrity level (ASIL) ratings against your system requirements before procurement.

Selection Notes

Select this component when a compact, integrated solution for three-phase BLDC control is required in automotive environments. Ensure the load current does not exceed the 3A continuous rating under worst-case thermal conditions. Consider external heat sinking if operating near maximum current limits.

Part Context

This part belongs to Texas Instruments' DRV32xx family of three-phase motor drivers. It is specifically engineered for automotive-grade reliability, offering a robust alternative to discrete MOSFET solutions by integrating drive logic and power stages into a single package.

Replacement Considerations

Check DRV3255 or DRV3253 variants for similar functionality with different pinouts or current ratings. Verify compatibility with existing PCB footprints and control signals when substituting.
