Note 2: The LTC4056E is guaranteed to meet performance specifications from 0 °C to 70°C ambient temperature range. Specifications over the –40 °C to 85°C operating ambient temperature range are assured by design, characterization and correlation with statistical process controls. Note 3: Although the LTC4056 will operate with input voltages as low as 4.5V, charging will not begin until VCC exceeds VUVCL. Note 4: Assumes that the external PNP pass transistor has negligible B-C reverse-leakage current when the collector is biased at 4.2V (VBAT) and the base is biased at 5V (VCC). Note 5: Assumes that the external PNP pass transistor has negligible B-E reverse-leakage current when the emitter is biased at 0V (VCC) and the base is biased at 4.2V (VBAT).
