DRV8353SMRTAT

Overview

The DRV8353SMRTAT is a three-phase smart gate driver manufactured by Texas Instruments, designed for driving power MOSFETs and IGBTs in motor control applications. It integrates six high-side and low-side half-bridge drivers within a single WQFN-40 package. The device supports a supply voltage range from 9 V to 100 V and delivers an output current of 1 A per channel. It operates within a temperature range of -55°C to +125°C and features a shutdown function with a maximum blanking time of 1 ms. The typical operating supply current is 8.5 mA.

Feature Summary

• Integrates three independent half-bridge drivers for complete three-phase motor control
• Supports high-voltage operation up to 100 V for robust power switching
• Includes integrated protection mechanisms such as under-voltage lockout and thermal shutdown
• Features a compact surface-mount WQFN-40 package for efficient PCB layout

Applications

• Brushless DC (BLDC) motor drives
• Three-phase AC induction motor control systems
• Industrial automation and robotics actuators
• Pump and fan control applications

Procurement Notes

Verify the specific suffix 'MRT' against the official Texas Instruments datasheet to confirm pinout compatibility and functional specifications. Ensure that the ordering information matches the required package type and tape-and-reel configuration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when a compact solution for three-phase motor driving is required with integrated logic and protection features. Consider the 100 V maximum rating and 1 A output current capability relative to the target power stage. Evaluate the WQFN-40 package constraints for thermal management and board space availability compared to alternative packages in the DRV8353 family.

Part Context

This part belongs to the DRV8353 series of smart gate drivers from Texas Instruments. It is specifically configured with the 'MRT' suffix indicating the WQFN-40 package variant. The series is designed to simplify the design of three-phase motor drives by integrating drivers, protections, and bootstrap diodes into a single IC, reducing component count and board area.

Replacement Considerations

DRV8353SRTAT: Alternative package variant within the same series offering similar electrical characteristics but potentially different pinout or thermal performance due to packaging differences.
