Overview

The MC121EVM enables users to evaluate the performance of the MC121 and MC121-Q1 single phase BLDC driver. The EVM includes an on-board FTDI chip to convert USB communication, from the PC, into UART. An on-board MSP430FR2355 microcontroller (MCU) translates the UART communication into either control signals or I2C formatted data, which is sent to the MC121 or MC121-Q1 in the application PCB. There are many userselectable jumpers, resistors, connectors, and test points to assist with evaluating the many features of the MC121 or MC121-Q1 and the configurable device-specific settings.

Features

One time programmable (OTP) write capability
GUI software to simplify the MC121 and MC121-Q1 tuning procedure and performance evaluation

Integrated control BLDC drivers

MC121-Q1 — Automotive, 40-V, 1-A peak single-phase BLDC Motor Driver with integrated hall sensor

MCF8316D-Q1 — Automotive 40-V max, 8-A peak, sensorless FOC control three-phase BLDC motor driver
