Product Summary
The MAX1879EUA single-cell lithium-ion (Li+) battery charger utilizes an efficient pulse-charging architecture to minimize power dissipation in portable devices. This architecture combines the efficiency of switch-mode chargers with the simplicity and low cost of linear chargers. The MAX1879EUA, in conjunction with a current-limited wall cube and a PMOS transistor, allows safe and fast charging of a single Li+ cell. The MAX1879EUA is offered in a space-saving 8-pin μMAX package. An evaluation kit(MAX1879EUAEVKIT) is available to help reduce design time.
