MLX10407
5-Channel Gauge Driver with Serial Link
2) 90° logometers
In addition to driving (2) 360° logometers the MLX10407 has a push-pull stage so it Is possible to
drive (3) additional 90° coils connected to GND or VDD respectively.
Serial Link
The MCU outputs the serial communication clock SCLK, the chip select CS, the data DIP, and
reads the ERRB error status.
The data sent by the MCU is latched by the 10407 on the rising edge of SCLK.
The 10407 outputs the ERRB signal on the falling edge of SCLK
When CS = "0" the serial interface of the 10407 is inactive. When CS goes HIGH, the 10407
waits for a START BIT and then reads the following 15 bits transmitted by the MCU.
The START BIT (D0) must be "1".

The following 10 bits (D4, D5, D6, D7, D8, D9, D10, D11, D12, D13) set the angle value (D13
=lsb, D4 = msb).
The two remaining bits (D14D15) represent the quadrant (D14=msb). Note: for Logo1 & 2 only.
