Overview
The MCT8316Z0TQRGFRQ1 is an automotive-grade, sensored trapezoidal control three-phase BLDC motor driver. It features integrated high-side and low-side power FETs with a maximum supply voltage of 40 V and peak output current of 8 A. The device operates within a temperature range of -40°C to +125°C and is housed in a VQFN-40 package. It includes built-in protection mechanisms such as overcurrent, overtemperature, undervoltage lockout, and short-circuit protection.
Feature Summary
- AEC-Q100 qualified for automotive applications
- Integrated three-phase half-bridge driver with internal FETs
- Sensored trapezoidal commutation control
- Comprehensive fault protection including OCP, OTP, and UVLO
Applications
- Automotive cooling fans
- Electric power steering systems
- Blower motors in HVAC units
- Pump control in automotive fluid management
Procurement Notes
Verify the specific suffix 'RGFR' corresponds to the reel packaging configuration required for your assembly line. Confirm that the 'Z0' variant matches the exact silicon revision needed for your design. Ensure the AEC-Q100 Grade 1 qualification aligns with your vehicle's thermal requirements. Cross-reference the ordering part number with the manufacturer's latest datasheet to avoid discrepancies in pinout or electrical characteristics.
Selection Notes
Select this component when designing for automotive environments requiring robust BLDC motor control with integrated power stages. It is suitable for applications needing sensored trapezoidal commutation rather than sensorless or sinusoidal methods. Consider the 40V rating and 8A peak current capability against your motor's specifications. The VQFN-40 package offers thermal performance benefits for compact designs.
Part Context
This part belongs to the MCT8316 family of integrated motor drivers from Texas Instruments. It is specifically engineered for automotive use, distinguishing it from non-automotive variants like the MCT8316A. The family focuses on simplifying BLDC motor control by integrating gate drivers, power FETs, and control logic into a single compact solution.
Replacement Considerations
Direct replacements include other parts within the MCT8316 family, such as the MCT8316A series, provided automotive qualification is not strictly required. Verify compatibility with existing PCB footprints and control algorithms when substituting with similar BLDC drivers from other manufacturers.
