                      Product Overview

                      The MAX1879EUA+ is a simple, efficient, 1-cell Li+ pulse charger in 8 pin µMAX package. This single cell lithium-ion (Li+) battery charger utilizes an efficient pulse charging architecture to minimize power dissipation. This architecture combines efficiency of switch mode chargers with simplicity and low cost of linear chargers. This simple device in conjunction with current limited wall cube and PMOS transistor allows safe and fast charging of a single Li+ cell. The MAX1879 initiates charging in one of three ways such as battery insertion, charger power-up or toggling THERM pin. It also includes continuous voltage and temperature monitoring, preset charger time-out and an 8mA pre-charge current mode to charge near dead cells. Automatic detection of input power removal shuts down the device which minimizes current drain from battery. An overall system accuracy of 0.75% ensures that the cell capacity is fully utilized without cycle life degradation.

                      • Input voltage from 4.6V to 22V at TA = -40°C to 85°C
                      • Operating temperature range from -40°C to 85°C
                      • Simple design minimizes heat and safely pre-charges near dead cells
                      • Low component count, no inductor and battery full indicator
                      • Pin compatible upgrade to MAX1679 device
                      • 1.5μA maximum battery current drain with wall cube removed
                      • Restart charging at 4V and BATT regulation voltage from 4.137V to 4.263V at TA = -40°C to 85°C
                      • Continuous overvoltage and overtemperature protection
                      • Charges 1 cell from as low as 4.5V
                      • Automatic power-down when power source is removed
