Overview
The DRV8353HRTAT is a three-phase smart gate driver with integrated pre-drivers and Hall-effect sensor signal conditioning, designed for brushless DC motor control. It operates within a supply voltage range of 6 V to 95 V and supports load voltages from 9 V 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 40-WQFN (6x6 mm) package with exposed pad for thermal management. The component functions across an extended temperature range of -40°C to +125°C and supports a switching frequency up to 200 kHz.
Feature Summary
- Integrates Hall-effect sensor signal conditioning with three-phase pre-drivers for simplified motor control designs
- Provides hardware-based commutation and direction management capabilities
- Supports power MOSFET technology for efficient gate driving
Applications
- Brushless DC (BLDC) motor control systems
- Multi-phase motor drive applications
- Industrial motion control equipment
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 25 mA output current specification meets the requirements for the intended power MOSFET gate drive application. Ensure the design accommodates the 40-WQFN package thermal characteristics for the expected operating environment.
Selection Notes
Select this component when hardware-based commutation logic is preferred over microcontroller-dependent software solutions. The integrated Hall-sensor conditioning reduces external component count compared to standard gate drivers. Consider the 25 mA output capability against the gate charge requirements of the target power stage.
Part Context
This part belongs to the DRV8353 family of smart gate drivers from Texas Instruments. It is specifically configured for BLDC motor applications requiring integrated sensing and control logic. The HRTAT variant denotes the specific packaging and reel configuration within the broader DRV8353 product line.
Replacement Considerations
DRV8353SRTAT is listed as a parameter-equivalent alternative by distributors.
