Status: In Production
System basis chip for three-phase brushless DC motor controllers designed in the Microchip 0.18-µm SOI technology SMART-I.S.™. The chip forms a BLDC motor control unit for automotive applications in combination with a microcontroller and six discrete power MOSFETs. Works in extended supply voltage range from 5.25V up to 32V.It features a T junction of up to 150°C. Its circuits provide a 3.3V/5V linear regulator and a window watchdog. It includes various control and protection functions like overvoltage and over-temperature protection, adjustable short circuit detection, undervoltage management and coast function. Its drivers fulfill maximum safety requirements and offer a high integration level to save cost and space.
Intention of the kit is demonstrating the features of the ATA6843/44 System Basis Chip BLDC Gate Driver. Motor position feedback operates with Back-Electromotive-Force (Back-EMF). Motor control microcontroller is ATmega32M1. For monitoring and evaluating purposes is an USB interface on board.
The application board allows loads to be easily adapted via its row connector pins. Design software controls its SPI interface via the PC parallel port. The board contains everything needed to start operation, including a link cable to PC 25-lead 1:1, application note and datasheet.
