These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 7.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins (1) ±2000 V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification JESD22-C101, ±500 all pins (2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 7.3 Recommended Operating Conditions MIN NOM MAX UNIT VAC Input voltage at AC pin 4.35 28 V VSYS Voltage at SYS pin 2.2 5.6 V IINUSB Input current at AC 500 mA IOUTSYS Output current at SYS 400 mA IBAT Average current into and out of BAT pin 300 mA VINDCDC1 Input voltage for step-down converter DCDC1 2.3 5.6 V VDCDC1 Output voltage for DCDC1 step-down converter; externally adjustable 0.6 VINDCDC1 V IOUTDCDC1 Output current at L 400 mA L Inductor at L(1) 2.2 3.3 4.7 μH VINLDO1 Input voltage for LDO1 1.8 VSYS V VLDO1 Output voltage for LDO1 0.8 3.3 V ILDO1 Output current at LDO1 200 mA CINAC Input capacitor at AC(1) 0.1 1 μF CBAT Capacitor at BAT(1) 0.1 4.7 μF CSYS Capacitor at SYS(1) 4.7 10 μF Input capacitor at VINDCDC1 (1); if connected to SYS, only one 4.7-μF capacitor CINDCDC1 4.7 μF required for SYS and CINDCDC1 COUTDCDC1 Output capacitor at VDCDC1 (1) 4.7 10 22 μF CINLDO1 Input capacitor at VINLDO1(1) 2.2 μF COUTLDO1 Output capacitor at LDO1(1) 2.2 μF (1) See Application and Implementation for more details.
