Overview
The DRV8350HRTVR is a three-phase smart gate driver from Texas Instruments designed for brushless DC motor applications. It integrates high-side and low-side drivers with an SPI interface for configuration. The device supports a supply voltage range of 6 V to 95 V and handles load voltages up to 75 V. It operates within a temperature range of -40°C to +125°C. The output current capability is specified at 25 mA, with a quiescent supply current of 8.5 mA. The component utilizes a WQFN-32 package and functions at frequencies up to 200 kHz.
Feature Summary
- Integrates intelligent gate driving capabilities for three-phase power stages
- Features serial peripheral interface (SPI) communication for control and monitoring
- Includes built-in protection mechanisms against over-current and thermal events
Applications
- Brushless DC (BLDC) motor drives
- Industrial automation systems
- Electric vehicle components
Procurement Notes
Verify the specific suffix HRTVR to confirm the reel packaging format and tape width. Ensure compatibility with the target PCB footprint for the WQFN-32 package. Confirm moisture sensitivity level handling procedures during assembly. Validate that the SPI pinout matches the controller design. Check for RoHS compliance status in the latest datasheet revision.
Selection Notes
Select this component when a 100-V rating is required for three-phase BLDC applications. Consider the integrated smart features if reducing external discrete components is a priority. Evaluate the WQFN-32 package size against available board space constraints. Compare the 25 mA output drive strength against the gate charge requirements of the selected MOSFETs. Assess the SPI interface complexity against the microcontroller resources available.
Part Context
This part belongs to the DRV835x family of smart gate drivers from Texas Instruments. The family shares common architectural features but varies in package options and specific electrical ratings. The DRV8350HRTVR specifically targets higher voltage applications compared to lower-voltage variants in the same series.
Replacement Considerations
The DRV8350HRTVTG4 is a lead-free variant of the same functional device. Verify pin-to-pin compatibility before substitution. Ensure the replacement meets the same thermal and electrical specifications.
