Abstract
An auto addressing scheme comprised of a central/master module and satellite/slave devices on a communication bus such as CAN that individually wakes the satellite devices alerting them when to listen to the CAN bus to receive their address, eliminating the need for a separate bus for auto addressing. The wake function is handled by low side n-channel MOSFET switches with current limiting resistors to protect the circuit against short to battery conditions and a voltage divider to step down the voltage to levels tolerable for a microcontroller input.
