with a resolution of 3.05μVh and a full-scale value of
±99.98mVh. When using a 50m Ω current sense resistor
this is equivalent to a resolution of 61.03μAh and a full-
scale value of 1.999Ah. Sign is set for negative values.
Register will be updated after setting bit UpdReq to “1”.

8.9.3 Charger Operation
The charger controls the battery current through the internal transistor between VSUP_SW1,2 and VBAT_SW1,2, the
step down charger and the battery switch between VSUPPLY and V BAT .
Charge Current Regulator
The regulator is programmed by setting TrickleCurrent and ConstantCurrent in the ChargerCurrent register and yields
a resolution of 0.625mV or 12.5mA when using a sense resistor of 50m Ω .
