Overview
The DRV8320SRTVR is a three-phase smart gate driver from Texas Instruments, designed for brushless DC motor applications. It integrates six high-side and low-side drivers within a single WQFN-32 package. The device supports a supply voltage range of 6 V to 60 V and delivers a peak output current of 1 A per channel. Key electrical specifications include a maximum operating temperature of +125 °C and a minimum of -40 °C. The component features hardware management interfaces alongside SPI/I2C connectivity for configuration.
Feature Summary
- Integrates smart gate drive technology with hardware management interfaces
- Supports both SPI and I2C communication protocols for digital control
- Provides integrated high-side and low-side half-bridge drivers
Applications
- Brushless DC (BLDC) motor control systems
- Industrial automation drives
- Robotics motion control platforms
Procurement Notes
Verify the specific suffix 'RVR' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with the intended PCB footprint, specifically the WQFN-32 package dimensions. Cross-reference the revision history to validate functional equivalence if substituting older versions. Confirm RoHS compliance status through official documentation before finalizing procurement.
Selection Notes
Select this component when a compact solution for three-phase BLDC motors is required within a 60 V system. The integrated smart gate drive reduces external component count compared to discrete solutions. Consider the WQFN-32 package for space-constrained designs. Verify that the 1 A output current meets the gate charge requirements of the target power MOSFETs or IGBTs.
Part Context
This part belongs to the DRV832x family of smart gate drivers. It is often evaluated using the BOOSTXL-DRV8320S development kit on the LaunchPad platform. The device serves as a bridge between microcontroller logic signals and high-power switching elements in motor drive circuits.
Replacement Considerations
The DRV8320SRTVT is a tape-and-reel alternative within the same series. Other variants like DRV8320HRTVR share similar electrical characteristics but may differ in packaging or specific interface configurations.
