DRV8302DCA

Overview

The DRV8302DCA is a three-phase brushless DC motor pre-driver manufactured by Texas Instruments. It integrates dual current sense amplifiers and a buck converter for system power management. The device operates on a single supply voltage ranging from 6 V to 60 V, with an absolute maximum rating of 65 V. It features a gate drive output current capability of 1.7 A and supports PWM control interfaces. The component is housed in a 56-pin HTSSOP package and is designed for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates dual low-side current shunt amplifiers for precise phase current monitoring.
• Includes an integrated buck step-down converter to provide regulated power for external logic or sensors.
• Utilizes bootstrap architecture with trickle charge support to enable high-side MOSFET driving at 100% duty cycle.
• Features integrated VDS detection to protect the external power stage from overcurrent conditions.

Applications

• Brushless DC (BLDC) motor control systems
• Electric vacuum cleaners
• Industrial motion control applications

Procurement Notes

Verify the specific revision level against the manufacturer datasheet to ensure compatibility with design requirements. Confirm that the HTSSOP-56 package footprint matches the PCB layout. Check moisture sensitivity levels and storage conditions prior to assembly. Ensure the input voltage range aligns with the system power supply specifications.

Selection Notes

Select this component when hardware-controlled three-phase gate driving is required alongside integrated current sensing. The built-in buck regulator simplifies power distribution in multi-voltage systems. Consider the 1.7 A peak drive current and 60 V operating limit when sizing external MOSFETs. This part is suitable for designs prioritizing reduced bill of materials through integrated signal conditioning and power regulation.

Part Context

The DRV8302 belongs to the DRV830x family of three-phase gate drivers from Texas Instruments. It is often paired with microcontrollers such as the TMS320F28035 for complete motor control solutions. The device serves as a bridge between digital control signals and high-power external switching elements, providing necessary isolation and amplification for efficient motor operation.

Replacement Considerations

The DRV8302DCAR is the reel-packaged variant of the same functional device. Other members of the DRV830x series may offer similar functionality but differ in pin counts or integrated features. Verify electrical parameters and package dimensions before substituting with other three-phase pre-drivers.
