Overview
The MCT8316A1VQRGFRQ1 is an automotive-grade, sensorless trapezoidal BLDC motor controller and driver from Texas Instruments. It integrates a half-bridge power stage capable of delivering an 8-A peak output current with a maximum supply voltage of 40 V. The device operates within a supply voltage range of 4.5 V to 35 V and supports I2C and PWM interfaces for control. Designed for harsh environments, it functions reliably across a temperature range of -40°C to +125°C and utilizes a 40-pin VQFN package.
Feature Summary
- Integrated sensorless trapezoidal control algorithm for brushless DC motors
- Automotive qualification compliant with AEC-Q100 standards
- Built-in protection mechanisms including overcurrent, thermal warning, and undervoltage lockout
Applications
- Automotive cooling fans and blowers
- Electric power steering systems
- Active grille shutters
Procurement Notes
Verify the specific suffix 'Q1' confirms automotive grade status against the official datasheet. Confirm the package type matches the design requirements. Ensure the ordering part number aligns exactly with the intended revision and tape-and-reel specifications provided by the manufacturer.
Selection Notes
Select this component when an integrated solution for automotive BLDC applications is required. It combines control logic and power drivers in a single chip. Consider the 8-A peak current capability and 40-V rating for system compatibility. Verify interface support for I2C or PWM based on the host microcontroller capabilities.
Part Context
This part belongs to the MCT8316 family of sensorless motor controllers. It is distinct from the DRV8316 series, which focuses on high-side/low-side gate driving rather than integrated sensorless control algorithms. The Q1 suffix indicates compliance with automotive reliability standards.
Replacement Considerations
MCF8316A1VRGFR is a commercial grade alternative without automotive qualification. DRV8316CRQRGFRQ1 is an automotive driver lacking integrated sensorless control logic.
