DRV8301QDCARQ1

Overview

The DRV8301QDCARQ1 is an automotive-grade three-phase brushless DC motor pre-driver designed for high-efficiency control applications. It integrates three half-bridge drivers capable of sourcing 1.7 A and sinking 2.3 A peak current, supporting N-channel MOSFETs up to 60 V. The device features two bidirectional current sense amplifiers with adjustable offset and a switch-mode buck converter delivering up to 1.5 A. Operating on a single supply from 6 V to 60 V, it includes SPI interface for parameter configuration and fault reporting. The component operates within a temperature range of -40 °C to +125 °C and is housed in a 56-pin HTSSOP package.

Feature Summary

• Integrates dual current sense amplifiers for precise bidirectional current measurement with adjustable output offset
• Includes an integrated switch-mode buck converter to provide system power for MCUs or other loads
• Features SPI interface for flexible parameter setting, including gain options and gate driver slew rate control
• Supports automatic handshake functionality to prevent shoot-through during high-side or low-side MOSFET switching

Applications

• Three-phase BLDC and PMSM motor drives
• Electric bicycles
• CPAP devices and pumps
• Robotics and remote-controlled toys
• Industrial automation systems

Procurement Notes

Verify the specific suffix 'QDCARQ1' against the official Texas Instruments datasheet to confirm the reel packaging variant and automotive qualification status. Ensure the ordering part number matches the required tape-and-reel quantity specifications. Cross-reference the AEC-Q100 grade requirements with your system's environmental standards before finalizing procurement.

Selection Notes

Select this component when designing three-phase motor control systems requiring integrated current sensing and gate driving capabilities. The inclusion of a buck converter simplifies bill of materials by eliminating external regulators for MCU power. Consider the 56-pin HTSSOP package constraints for PCB layout and thermal management. Verify that the 6 V to 60 V input voltage range aligns with the target motor supply voltage.

Part Context

This device belongs to the DRV8301 family of three-phase pre-drivers from Texas Instruments. It is specifically engineered for automotive applications, meeting AEC-Q100 reliability standards. The QDCARQ1 designation indicates the automotive grade, HTSSOP-56 package, and reel packaging format. It serves as a key interface between microcontrollers and power MOSFETs in electric drive systems.

Replacement Considerations

Consult the official Texas Instruments product selection guide for verified alternative part numbers within the DRV8301 series. Confirm pin-to-pin compatibility and electrical parameter equivalence before substitution. Do not assume functional interchangeability with non-automotive grades or different package variants without explicit manufacturer validation.
