1.5.4 Battery charger (LEON-G200 only)

For battery charging functionalities the module is provided with integrated circuitry and software. Two pins are
available to connect the positive pole of the external DC supply used as charger.
Name Description
V_CHARGE Charger Voltage Supply Input
CHARGE_SENSE Charger Voltage Measurement Input
Table 8: Battery charger pins
V_CHARGE and CHARGE_SENSE pins ESD sensitivity rating is 1 kV (HBM JESD22-A114F). A higher
protection level could be required if the lines are externally accessible on the application board. A higher
protection level can be achieved mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor
array) on the lines connected to these pins if they are externally accessible on the application board.
