MCF8315C1VRRYR

Overview

The MCF8315C1VRRYR is a fully integrated three-phase BLDC motor driver featuring sensorless Field Oriented Control (FOC). It supports a maximum supply voltage of 40V and delivers a peak output current of 4A. The device operates within an ambient temperature range of -40°C to 125°C and accepts supply voltages between 4.5V and 35V. Designed for speed-controlled 12V to 24V brushless-DC motors, it combines control logic with power stages in a single chip.

Feature Summary

• Integrates code-free sensorless Field Oriented Control algorithm for precise motor management
• Combines fully integrated control and power stage functions on a single chip
• Supports multiple interface protocols including Analog, I2C, and PWM inputs

Applications

• Speed-controlled 12V to 24V brushless-DC motors
• Permanent magnet synchronous motors
• General purpose motor control systems

Procurement Notes

Verify the specific suffix '1VRRYR' against the manufacturer's official ordering guide to confirm package type and tape/reel specifications. Ensure the automotive-grade variant MCF8315C-Q1 is not required if AEC-Q100 compliance is necessary for the target application environment.

Selection Notes

Select this component when a compact, single-chip solution for sensorless FOC is required. It is suitable for applications needing integrated power stages without external gate drivers. Consider the 4A peak current limit and 40V absolute maximum rating when designing the power stage.

Part Context

This part belongs to the MCF8315C series of sensorless FOC integrated FET BLDC motor drivers from Texas Instruments. The series provides a complete solution for driving permanent magnet motors without position sensors, simplifying system design by reducing component count.

Replacement Considerations

The MCF8315C-Q1 is the automotive-qualified version of this device. Verify if automotive reliability standards are required before substituting.
