6.5 Programming the MLX90320 through the output pin
Communicating with the MLX90320 only requires a limited amount of interface circuitry, software and a
computer. Melexis provides a communication equipment and belonging software such that the customer is able
to start communicating with the chip in a matter of minutes.
The output pin acts as analog output pin and as communication pin.
The drive stage of a class AB amplifier is connected to that pin to output the analog output signal.
For the communication the output will be sink/source current source.
Through a short circuit detection, the ASSP knows that the user requests the pin for communication.
6.5.1 Overview
When the user wants to communicate with the MLX90320, communication must be requested.
This can be achieved by short-circuiting the output pin to ground and supply level.
The ASSP detects this short and after a delay time, the same output pin turns into a half-duplex digital
communication channel.
