5.1 Detailed Description
Integrated on each individual IC within the MLX90277 is a temperature-compensated quad switched Hall
plate, chopper stabilized amplifiers, adjustable output filter, output driver, voltage protection circuitry and a
programmable EEPROM with security and redundancy. Programming the EEPROM allows each device to be
calibrated in the application.
In normal operation data stored in the EEPROM feeds a register, RAM, that updates internal DACs and
switches that effect the operation of the device. In programming mode the RAM can be directly accessed to
allow faster calibration of the parameters. Communication to the device is done using Melexis' PTC serial
interface.
