DRV8353SRTAR

Overview

The DRV8353SRTAR is a three-phase smart gate driver manufactured by Texas Instruments, designed for brushless DC motor control applications. It integrates high-side and low-side drivers with an onboard controller supporting SPI interface communication. The device operates within a supply voltage range of 6 V to 95 V and supports load voltages up to 75 V. It features a maximum output current capability of 25 mA per channel and maintains a quiescent supply current of 8.5 mA. The component functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a 40-pin WQFN package with dimensions of 6x6 mm, facilitating surface-mount installation.

Feature Summary

• Integrates three-phase smart gate drivers with onboard control logic for simplified system design
• Supports digital configuration and monitoring via Serial Peripheral Interface (SPI)
• Provides integrated protection mechanisms including over-current, over-temperature, and under-voltage lockout

Applications

• Brushless DC (BLDC) motor drives
• Industrial automation systems
• Robotics motion control

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the 40-WQFN footprint matches the target PCB layout. Ensure the input voltage does not exceed the 95 V absolute maximum rating. Check RoHS compliance status if required by regional regulations. Validate that the SPI interface signals are compatible with the host microcontroller logic levels.

Selection Notes

Select this component for applications requiring integrated gate driving and control in a compact form factor. The 25 mA output current suits standard MOSFET or IGBT switching requirements. Consider the WQFN-40 package for thermal performance and space constraints. Verify compatibility with the desired motor type, specifically BLDC configurations. Evaluate the SPI interface needs against available microcontroller resources.

Part Context

This part belongs to the DRV8353 series of three-phase smart gate drivers from Texas Instruments. It is distinct from the DRV8353FS variant which focuses on functional safety certification. The SRTAR designation specifies the standard commercial grade version in a tape-and-reel format. It shares core functionality with other members like the DRV8353RSRGZT but differs in package type and pin count.

Replacement Considerations

DRV8353HRTAR is listed as a parameter-equivalent alternative.
