Overview
The DRV8353HMRTAT is a smart gate driver from Texas Instruments designed for three-phase brushless DC motor applications. It integrates six high-side and low-side drivers with a maximum supply voltage of 100 V. The device operates within a temperature range of -55°C to +125°C and features an 8.5 mA operating supply current. It utilizes a WQFN-40 package and supports PWM inputs up to 200 kHz. The component includes built-in protections such as under-voltage lockout, over-current protection, and thermal shutdown.
Feature Summary
- Integrates six half-bridge drivers for complete three-phase motor control
- Includes integrated bootstrap diodes for simplified external component count
- Features programmable dead-time control to prevent shoot-through currents
- Provides comprehensive protection against over-current, over-temperature, and under-voltage conditions
Applications
- Brushless DC (BLDC) motor drives
- Industrial automation systems
- Electric power steering (EPS)
- Pump and fan control applications
Procurement Notes
Verify the specific suffix 'M' indicates automotive-grade qualification or material compliance distinct from standard industrial variants. Confirm the 'TAT' suffix corresponds to the correct reel packaging quantity and tape-and-reel specifications required for your assembly line equipment. Ensure compatibility with your PCB footprint for the WQFN-40 package.
Selection Notes
Select this component when driving three-phase BLDC motors requiring high-side and low-side gate drive integration. Consider the 100 V rating for higher voltage bus applications. Evaluate the -55°C to +125°C operating range against your environmental requirements. Compare output current capabilities and protection features against other devices in the DRV835x family.
Part Context
This part belongs to the DRV8353 series of smart gate drivers. It is functionally related to the DRV8353HRTAT but may differ in automotive qualification status or specific material certifications. The series is designed to simplify the design of three-phase motor control systems by integrating necessary driver stages and protection logic into a single compact package.
Replacement Considerations
DRV8353HRTAT is listed as a parameter-equivalent alternative. Verify if the 'M' suffix denotes specific automotive or enhanced reliability standards that are critical for your application before substituting.
