EXTERNAL RESISTOR FOR V_WEAK_SET

The ADP5065 charger features a VWEAK threshold, which can be

used for enabling the main PMU system. When battery voltage

at the BAT_SNS pin exceeds the VWEAK level, the ADP5065 pulls

down the SYS_ON_OK open-drain flag.

The VWEAK threshold can be programmed set either by I2C or by

an external resistor connected between the V_WEAK_SET pin

and GND. Recommended resistor values for each threshold are

listed in Table 13.

If an external resistor is not used, it is recommended to tie the

V_WEAK_SET pin to AGND for VWEAK to obtain its default value.
