3 / 18 page © 2008 Semtech Corporation SC802/SC802A 3 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) VCC1 and VCC2, and VOUT1 and VOUT2, must be connected, and will be referred to collectively as VCC and VOUT, respectively. All references to V VCC , V VOUT , I VCC , and I VOUT refer to the common node voltage and total current of VCC1 and VCC2, and VOUT1 and VOUT2, respectively. (2) Tested according to JEDEC standard JESD22-A114-B. (3) Operating voltage is the input voltage at which the charger is guaranteed to begin operation. Maximum operating voltage is the maximum Vsupply as defined in EIA/JEDEC Standard Number 78, paragraph 2.11. (4) 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.
