Hello world;
as I understand, CM4 and CM5 require a minimum rise time of the 5V supply voltage in order to start. In case the supply voltage rises too slowly how can I guarantee that the CM starts. My idea is using something like the MCP120-485 voltage supervisor (https://ww1.microchip.com/downloads/en/ ... 11184d.pdf) that holds Reset low until the voltage has reached 4.75V. I would connect the MCP120's Reset pin to CM PMIC_EN input (pin 99).
Would this work?
