21 / 67 page

Note 1:

All devices are 100% production tested at TA = +25°C. Limits over the operating temperature range guaranteed by

design.

Note 2:

This value is included in the IBAT quiescent current values for the ON states.

Note 3:

When the die temperature exceeds TCHGIN_SHDN, the CHGIN to SYS path opens, and the charger is turned off.

Note 4:

When the die temperature exceeds TCHG_LIM, the charger current starts to decrease.

Note 5:

This is the threshold at which the charger starts to limit the current due to SYS dropping; if VSYS drops below this value

the charger will not move to maintain charge.

Note 6:

Fast charge current accuracy tested only at 50mA and 500mA, all other values guaranteed by design.

Note 7:

Values over temperature are not production tested and guaranteed by characterization.

Note 8:

fSCL must meet the minimum clock low time plus the rise/fall times.

Note 9:

The maximum tHD:DAT has to be met only if the device does not stretch the low period (tLOW) of the SCL signal.

Note 10: Filters on SDA and SCL suppress noise spikes at the input buffers and delay the sampling instant.

(VCHGIN = 5.0V, VBAT = 3.7V, TA = -40°C to +85°C, all registers in their default state, unless otherwise noted. Typical values are at

TA = +25°C.) (Note 1)
