Overview
The DRV8301DCAR is a three-phase brushless motor pre-driver manufactured by Texas Instruments, housed in a 56-pin HTSSOP package. It operates on a single supply voltage ranging from 6 V to 60 V and supports an output current of 1.7 A with a peak capability of 2.3 A. The device integrates dual current sense amplifiers for precise bidirectional current measurement and includes an integrated switching mode buck converter capable of delivering up to 1.5 A. It functions within a temperature range of -40°C to +125°C and utilizes SPI for configuration.
Feature Summary
- Integrates three half-bridge drivers supporting N-channel MOSFETs with bootstrap architecture for 100% duty cycle operation.
- Includes two current sense amplifiers providing adjustable output offset and support for bidirectional current detection.
- Features an integrated switch-mode buck converter with adjustable output and switching frequency to supply system power.
- Provides hardware-level protection mechanisms including overcurrent, overtemperature, undervoltage lockout, and cross-conduction prevention.
Applications
- Three-phase BLDC and PMSM motor drives
- CPAP devices and pumps
- Electric bicycles
- Power tools
- Robotics and remote control toys
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the HTSSOP-56 package dimensions match your PCB footprint requirements. Ensure the 6 V to 60 V operating voltage range aligns with your system design. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly. Validate that the SPI interface compatibility matches your microcontroller setup.
Selection Notes
Select this component for applications requiring integrated gate driving and current sensing without external analog components. Consider the 1.7 A continuous output current against your motor load requirements. Evaluate the need for the integrated buck converter to simplify power distribution. Verify thermal performance capabilities within the specified -40°C to +125°C ambient range. Ensure SPI communication protocols are supported by your host controller.
Part Context
The DRV8301DCAR belongs to the DRV8301 series of three-phase pre-drivers designed for high-efficiency motor control. It serves as a bridge between digital controllers and power MOSFETs, simplifying system design by integrating critical analog functions. This series is widely used in industrial and consumer motor applications requiring robust protection and precise control.
Replacement Considerations
DRV8301DCA is a tube-packaged equivalent within the same series. DRV8301QDCAQ1 is an automotive-grade variant with AEC-Q100 qualification. Verify pinout and electrical specifications before substitution.
