Overview
The DRV8320RSRHAR is a three-phase smart gate driver from Texas Instruments, designed for brushless DC motor control applications. It operates within a supply voltage range of 6 V to 60 V and supports peak source and sink currents of 1 A and 2 A respectively. The device integrates hardware management interfaces alongside SPI/I2C capabilities for configuration. It utilizes a 48-pin PowerPAD VQFN package suitable for surface-mount installation. The component functions across an extended temperature range from -40°C to +125°C, ensuring reliability in demanding environments.
Feature Summary
- Integrates smart gate drive architecture with adjustable slew rate and dead-time control
- Supports hardware management interface for simplified system integration
- Enables digital configuration via SPI or I2C communication protocols
Applications
- Brushless DC (BLDC) motor drives
- Three-phase motor control systems
- Industrial automation equipment
Procurement Notes
Verify the specific suffix 'HAR' against the official datasheet to confirm pinout and thermal pad specifications. Ensure compatibility with the intended PCB footprint and thermal management strategy. Confirm that the required current sensing amplifiers are not needed, as this variant lacks integrated shunt amplifiers compared to other models in the series.
Selection Notes
Select this component when a compact solution for three-phase BLDC motors is required without integrated current sensing. It is suitable for designs where external current monitoring is preferred or already implemented. Consider the 48-pin package size relative to available board space. Verify that the 6V to 60V input range matches the system power supply constraints.
Part Context
This part belongs to the DRV832x family of three-phase smart gate drivers. Unlike the DRV8323 variants, it does not include integrated current sense amplifiers. It shares similar gate drive performance and interface options with other members of the series but offers a distinct feature set tailored for cost-sensitive or externally sensed applications.
Replacement Considerations
Direct substitutes include other DRV8320 variants such as DRV8320SRTVR or DRV8320HRTVR, depending on package and feature requirements. Cross-referencing with DRV8323 models is possible if integrated current sensing is acceptable.
