MCF8316C1VQRGFRQ1

Overview

The MCF8316C1VQRGFRQ1 is an automotive-grade, single-chip integrated FET BLDC driver designed for sensorless field-oriented control (FOC). It supports a maximum supply voltage of 40 V and delivers an 8 A peak output current. The device operates within a temperature range of -40°C to +125°C and is housed in a VQFN-40 package. It integrates high-side and low-side N-channel power MOSFETs with a dedicated gate drive circuit.

Feature Summary

• Integrates sensorless FOC algorithm execution with power stage components on a single chip
• Includes built-in protection mechanisms against overcurrent, overvoltage, undervoltage, and overheating
• Supports programmable dead-time adjustment and configurable PWM input frequencies

Applications

• Automotive cooling fans and blowers
• Electric power steering systems
• Throttle body actuators

Procurement Notes

Verify the specific suffix 'C1' matches the required feature set, as it denotes specific configuration options compared to other variants in the MCF8316 family. Confirm AEC-Q100 Grade 1 qualification requirements are met for the target automotive application environment before finalizing component selection.

Selection Notes

Select this component when a code-free, sensorless FOC solution is required for three-phase BLDC motors in automotive environments. Ensure the system design accommodates the 40 V maximum voltage rating and that thermal management strategies support the VQFN-40 package's heat dissipation capabilities under peak load conditions.

Part Context

This part belongs to the Texas Instruments MCF8316D-Q1 series, which focuses on integrated motor control solutions. Unlike standard half-bridge drivers, this series combines the controller logic and power FETs, simplifying the bill of materials and reducing board space requirements for complex motor control applications.

Replacement Considerations

MCF8316DVQRGFRQ1: Similar automotive BLDC driver but may differ in specific FOC integration or pinout configurations. Verify functional compatibility and parameter alignment before substitution.
