Overview
The DRV8350FSRTVR is a three-phase smart gate driver from Texas Instruments designed for brushless DC motor applications. It operates within a supply voltage range of 6 V to 95 V and supports load voltages from 9 V to 75 V. The device features an integrated LM5008A buck regulator capable of delivering up to 350 mA at output voltages between 2.5 V and 75 V. It provides a peak source current of 25 mA and a peak sink current of 1 A. The component utilizes a 32-WQFN (5x5 mm) package with surface mount installation and functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-voltage buck regulator for external power supply generation
- Includes three configurable current sense amplifiers for precise motor control
- Supports multiple PWM modes including 6x, 3x, 1x, and independent configurations
Applications
- Three-phase brushless DC motor modules
- Fans, blowers, and pumps
- Electric bicycles and scooters
- Power tools and lawn mowers
Procurement Notes
Verify the specific suffix 'F' indicates the inclusion of the integrated buck regulator and current sense amplifiers, distinguishing it from standard variants. Confirm the WQFN-32 package dimensions and moisture sensitivity level requirements during storage and handling. Ensure the SPI interface configuration matches the host controller capabilities before finalizing procurement specifications.
Selection Notes
Select this variant when system design requires an integrated high-current buck regulator to power external microcontrollers or sensors. The presence of built-in current sense amplifiers reduces external component count compared to non-integrated versions. Evaluate the thermal performance of the 32-WQFN package against the expected junction temperature rise under maximum load conditions.
Part Context
This component belongs to the DRV835xF family of smart gate drivers. The 'F' designation specifically denotes the integration of the LM5008A buck converter and current sense amplifiers. This distinguishes it from the DRV8350S series, which lacks these specific integrated features but shares the same core gate driver architecture and pinout compatibility.
Replacement Considerations
DRV8350SRTVT serves as a functional substitute if the integrated buck regulator and current sense amplifiers are not required by the application design.
