Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters
specified in the Electrical Characteristics section is not recommended.
NOTES:
(1) Tested according to JEDEC standard JESD22-A114.
(2) Operating Voltage is the input voltage at which the charger is guaranteed to begin operation. These ranges apply to charging sources
operating in voltage regulation. Charging sources operating in current limit may be pulled below these ranges by the charging load.
Maximum operating voltage is the maximum Vsupply as defined in EIA/JEDEC Standard No. 78, paragraph 2.11.
(3) Calculated from package in still air, mounted to 3 x 4.5 (in), 4 layer FR4 PCB with thermal vias under the exposed pad per JESD51 standards.
Electrical Characteristics
Test Conditions: V VIN = 5.00V (1) , V BAT = 3.70V unless specified; Typ values at 25°C; Min and Max at -40°C < T A < 85°C, unless specified.
