BQ24773 data sheet shows ILIM must be connected to a voltage divider referenced to a supply rail, but it does not define 'supply rail'. There are 5 in our application,
1) Adapter Supply Voltage
2) Battery Voltage
3) Vsys
4) Regulated +5V, downstream fed by Vsys
5) Vregn [pin 24]
I am assuming we must use a regulated source since we want a fixed voltage reference for ILIM, but can I use Vregn as the supply rail? I do not want any downstream regulated sources as these will be off when the device is in low power mode.
Please clarify.
Thanks
