48 / 160 page  Page 48 ams Datasheet, Confidential Document Feedback [v1-00] 2014-Sep-10 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) Figure 47: MIN/MAX Temp Supervision MIN/MAX Temp Supervision Diagram: Shows the voltage and current settings for the MIN/MAX temperature supervision. (EQ3) (EQ4) T1upper TEMPERATURE [°C] CHARGE CURRENT CHARGE VOLTAGE Maximum Charge Current: 1C Typical Charge Voltage: Veoc(typ) 3.5V <Veoc(typ) <4.44V 750mA < Icc_normal(typ) < 1500mA 60mA < Itrickle(typ) < 240mA COLD TYPICAL HOT Charger is OFF Charger is OFF 350mA < Icc_low(typ) < 750mA T1lower T4upper T4lower |
