Typical (Typ) specifications are mean or average values 25 °C and are not guaranteed. Unless otherwise noted: VBAT = 3.7 V, VDD_SYS = 3.7 V, VDD_PWR = 5.0 V, VDDIO = 1.8 V, and TA = -40 °C to 85 °C. 2.4.1 Battery Charger Table 6: Battery Charger Parameter Description Conditions Min Typ Max Unit Electrical Performance VDD_SYS_THR _DPPM VDD_SYS DPPM voltage threshold VDD_SYS falling, above VBAT_CHG 0.2 V RON_CHG_INT Battery charger MOSFET on resistance Measured from VBAT to VDD_SYS 300 400 mΩ VDROP_BAT_T O_VDD_SYS VBAT - VDD_SYS VBAT > 3 V, IBAT discharge = 400 mA 120 160 mV VBAT_SUP Threshold to enter the battery supplement mode VVBAT > VVBAT_UVLO VDD_ SYS < VBAT V IBAT_DCHG_RN G Discharge current limit setting range Selectable 0.2 A / step 0.55 1.75 A VBAT_CHG Charge voltage range Operating in voltage regulation, programmable range in 10 mV steps 3.6 4.65 V VBAT_CHG_AC C Charge voltage accuracy 0 °C< TJ < 85 °C -0.5 0.5 % ICHG Fast charge current range 2 500 mA ICHG_ACC Fast charge current accuracy -5 5 % ITER_RNG Termination and pre-charge current setting range Termination current programmable range maximum over I2C 0.5 50 mA ITER_ACC Termination charge current accuracy Peak current below termination threshold -10 10 % tTER_DEGLITCH Termination deglitch time Charge current falling 64 ms |
