Overview
The DRV8353SRTAT is a three-phase smart gate driver with an integrated motor controller, designed for brushless DC (BLDC) applications. It operates within a supply voltage range of 6 V to 95 V and supports load voltages up to 75 V. The device features a maximum output current of 25 mA per channel and consumes 8.5 mA in quiescent operation. It utilizes a WQFN-40 package and supports a working frequency of 200 kHz. The component functions across an extended temperature range from -40°C to +125°C.
Feature Summary
- Integrates a three-phase smart gate driver with a dedicated BLDC motor controller for simplified system design.
- Supports both hardware control interfaces and serial peripheral interface (SPI) communication for configuration.
- Includes built-in protection mechanisms such as over-current protection and thermal shutdown for reliable operation.
Applications
- Brushless DC (BLDC) motor control systems
- Industrial automation drives
- Home appliance motor management
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the device requires external power MOSFETs for high-side and low-side switching, as the DRV8353SRTAT functions as a gate driver and controller rather than an integrated power stage. Ensure compatibility with the required SPI or hardware control signals for the target application.
Selection Notes
Select this component for designs requiring a compact solution for three-phase BLDC motors with moderate current requirements. It is suitable for applications where space constraints favor the WQFN-40 package. Consider the 25 mA output drive capability against the gate charge requirements of the selected external MOSFETs to ensure adequate switching performance.
Part Context
This part belongs to the Texas Instruments DRV8353 series of smart gate drivers. It serves as a specialized solution for controlling three-phase motors, distinguishing itself from general-purpose gate drivers by including integrated commutation logic. The series offers variants with different packaging and interface options to suit various manufacturing and design needs.
Replacement Considerations
The DRV8353HRTAT is documented as a parameter-equivalent alternative, differing primarily in its hardware-only interface configuration compared to the SPI-capable DRV8353SRTAT.
