Linear Li+Battery Charger with Integrated Pass FET
and Thermal Regulation in 3mm x 3mm Thin DFN
ELECTRICAL CHARACTERISTICS (continued)
(V_IN = 5V, V_BATT = 4.0V, TEMP = EN = CHG = unconnected, R_ISET = 2.8kΩ to GND, C_VL = 0.47µF, BATT bypassed to GND with 1µF,
T_A = -40°C to +85°C, unless otherwise noted. Typical values are at T_A = +25°C.) (Note 1)
