DRV8353RFSRGZR

Overview

The DRV8353RFSRGZR is a 100-V three-phase smart gate driver from Texas Instruments, housed in a 48-VQFN package. It integrates an optional buck regulator and triple low-side current shunt amplifiers. The device supports supply voltages from 9 V to 100 V and operates within a temperature range of -40°C to 125°C. Key interfaces include SPI/I2C for configuration and multiple PWM inputs for control.

Feature Summary

• Integrates a buck converter for internal power regulation
• Includes three low-side current shunt amplifiers for precise sensing
• Supports hardware management interface alongside digital communication

Applications

• Brushless DC (BLDC) motor drives
• Stepper motor controllers
• Industrial automation systems

Procurement Notes

Verify the specific suffix 'FS' against the manufacturer's official datasheet to confirm the presence of integrated features such as the buck regulator and current sense amplifiers. Ensure the ordering part number matches the exact package and tape/reel specifications required for your assembly process.

Selection Notes

Select this component when a high-voltage three-phase gate driver with integrated power management and current sensing is required. It is suitable for designs needing reduced external component count and simplified layout compared to discrete solutions.

Part Context

This part belongs to the DRV835xF family of 100-V three-phase smart gate drivers. The family offers various configurations with or without integrated regulators and amplifiers, allowing designers to choose the optimal balance between functionality and cost for motor control applications.

Replacement Considerations

Check the DRV8353RSRGZR datasheet for pin-to-pin compatibility if the integrated features are not needed. Verify that any substitute maintains the same voltage ratings and package dimensions.
