DRV8303DCA

Overview

The DRV8303DCA is a three-phase pre-driver with dual current shunt amplifiers, manufactured by Texas Instruments. It operates within a supply voltage range of 6 V to 60 V and supports output currents up to 1.7 A. The device features an HTSSOP-48 package and functions across a temperature range of -40°C to +125°C. It includes integrated current sensing amplifiers with programmable gain, SPI interface for configuration, and comprehensive protection mechanisms including overcurrent, undervoltage lockout, and overtemperature shutdown.

Feature Summary

• Integrates two high-performance current shunt amplifiers with programmable gain settings for precise low-side or series current measurement.
• Features a bootstrap gate driver architecture supporting 100% duty cycle operation with adjustable peak gate drive current and internal dead time.
• Provides flexible control modes via SPI interface, supporting both 6-PWM and 3-PWM input configurations for advanced motor control applications.

Applications

• Brushless DC (BLDC) motor control systems
• Three-phase permanent magnet synchronous motor (PMSM) drives
• Industrial motion control and automation equipment

Procurement Notes

Verify the specific suffix 'DCA' corresponds to the tube packaging variant when ordering, distinct from the 'DCAR' reel version. Confirm the HTSSOP-48 package dimensions match your PCB footprint requirements. Ensure compatibility with your system's voltage levels, as the device requires a 6V to 60V supply range. Check for moisture sensitivity handling procedures during storage and assembly, as indicated in the datasheet specifications.

Selection Notes

Select this component when designing three-phase motor drives requiring integrated current sensing without external amplifiers. It is suitable for applications needing SPI-based parameter tuning and fault reporting. Consider the 1.7A output capability and thermal performance in the HTSSOP-48 package against your load requirements. Evaluate the need for bootstrap drive support and 100% duty cycle operation for your specific motor topology.

Part Context

The DRV8303DCA belongs to the DRV8303 family of three-phase pre-drivers from Texas Instruments. It is designed to work alongside microcontrollers like the TMS320F2803x for complete motor control solutions. The device simplifies design by integrating gate drivers and current sense amplifiers, reducing component count compared to discrete solutions. It is part of TI's broader portfolio of power management and motor control ICs.

Replacement Considerations

Direct substitutes include other parts in the DRV8303 family, such as DRV8303DCAR, which shares identical electrical characteristics but differs in packaging format. Verify pinout and functional equivalence before swapping variants within the same series.
