AS3715 − Detailed Description – Power Management Functions

The base values (T1min, T2min, T3min and T3min) for the

comparator levels are marked in the table above. To adjust the

comparator levels to the needed temperature levels dedicated

adjust bits can be set (32-64 7mV steps).

Txlim_upper=Txmin + Tx_adj * 7mV

Also the hysteresis of the ON and OFF levels can be programmed

(4bits with 16 7mV steps).

Txlim_lower=Txlim_upper + (Tx_hyst + 3) * 7mV

Charger MIN/MAX Temp Supervision

The simpler supervision mode is supervising T1 (0°C) and

T4 (60°C)
