TIDRV8353SMRTAT

Overview

The DRV8353SMRTAT is a highly integrated 100V gate driver designed for three-phase brushless DC (BLDC) motor applications. It features a smart gate drive architecture that optimizes MOSFET switching while reducing EMI and eliminates the need for external gate resistors. The 'S' variant includes an SPI interface for detailed configuration and fault reporting, alongside three integrated current shunt amplifiers for precise torque control.

Why Choose This Part

This driver simplifies system design by integrating three current shunt amplifiers and a linear regulator, reducing the overall bill of materials. The smart gate drive architecture allows for adjustable slew rate control to manage EMI and includes hardware-level shoot-through prevention. It also offers robust protection including VDS overcurrent monitoring and thermal shutdown to ensure long-term reliability in harsh industrial environments.

Applications

Getting Started

Start development with the DRV8353RS-EVM evaluation module, which provides a complete reference platform for testing motor performance. Configure the device settings, such as gate drive current and shunt amplifier gain, using the SPI interface via a microcontroller like a C2000 or MSP430. Ensure the 40-WQFN thermal pad is properly soldered to a large ground plane to manage heat dissipation at high voltages.
