The battery pack voltage is fixed at 4.2 V, and the maximum charge current is 950 mA — set by an external resistor on the PROG pin. The programmable current feature (via the PROG pin) lets the BOM engineer scale the charge rate down for smaller cells or thermal constraints without changing the IC. ## Supply and temperature envelope The charger operates from a supply voltage up to 6.5 V (max) and draws the charge current from the input rail.","metaTitle":"LTC4058EDD-4.2#PBF Li-Ion Charger IC, 950 mA, 8-DFN","metaDescription":"LTC4058EDD-4.2#PBF single-cell Li-Ion battery charger, 950 mA max charge current, 8-WFDFN package, -40 to 85°C.
