Abstract

The MCF83xx and MCT83xx devices are code-free, easy-to-use, highly configurable three-phase BLDC drivers with integrated motor control. These devices have an internal EEPROM to store the motor tuning and system level configurations like current limit, motor acceleration time, maximum speed, PWM switching frequency, supply overvoltage or undervoltage threshold, and so on. These configurations stored in the internal EEPROM are used to initialize the device on every power-up or wake-up. This application note explains the procedure for reading from and writing to this internal EEPROM.

Note:
  • MCF83xx refers to TI’s sensorless FOC based 3-phase BLDC drivers including MCF8316D, MCF8315D, MCF8316C-Q1, MCF8315C-Q1, MCF8315C, MCF8315A, MCF8316A and MCF8329A.
  • MCT83xx refers to TI’s sensorless trapezoidal commutation based 3-phase BLDC drivers including MCT8316A, MCT8316A-Q1, MCT8315A and MCT8329A.
  • MCF83xx and MCT83xx family of devices are referred to as MCx devices in this application note.
