Electrical characteristics
Charger vs. battery
The ConnectCore for i.MX51 can be supplied solely either through the battery input or also through
the charger input, although the VLIO input is the preferred method. When using solely the charger
input, and when no battery is connected to VLIO, the ConnectCore for i.MX51 will not be functional
across the entire rated temperature of the product. As an example, when using the product at -20C,
the ConnectCore for the i.MX51 will not be functional due to the internals state machine of the module
PMIC.
To override this limitation for all instances, you must generate a battery voltage on the carrier board.
Different options are available for simulating a battery voltage - below is one example, based on three
Schottky diodes in series.
