Connect a resistor (RITER_CHG) from the ITER_CHG pin to ground. Table 32 shows the recommended

resistor values to set the pre-charge and termination currents.

Once VDD_PWR is connected, ICHG_PRE and ITER values can be read at register 0x0020 [5:4].

ICHG_PRE cannot be set higher than 50 mA, or lower than 0.5 mA. Settings which are out of range

result in the minimum or maximum current setting. For example, with a 400 mA fast charge current, a

20 % setting would result in 80 mA, but the actual pre-charge current is the maximum value, 50 mA.

Input Current Limit Programming

VDD_PWR input current limit (IDDPWR_LIM) is programmed by a resistor connected from the ILIM_PWR

pin to ground. The resistor value is calculated as:

��_��(Ω) =

1000

Not all current limit register settings are available in Resistor Setting mode. The available current limit

settings and corresponding resistor values are shown in Table 33.

Charge Current Programming

Fast charge current (ICHG) is programmed by a resistor connected from the ILIM_CHG pin to ground.

The resistor value is calculated as:
