AS3715 − Detailed Description – Power Management Functions

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)
