We are planing to use the ADM1178 Hot swap controller in a new design and want to control it fully via the I2C interface. The Datasheet does not provide enough information if this is possible.
1. If the ON Pin is always grounded (FET = off), can it be turned On and Off via an I2C command without using the ON pin?
In case this can be done, then I have the following questions:
2. If the FET is turned on via a Software command via I2C and then the ON pin is toggled high and low, will the FET turn off or has the Software command priority?
3. How does the Hardware pin interact with the Software On/Off Command?
Thanks for any help,
