Overview

19-2295; Rev 0; 1/02 Linear Charger for Single-Cell Li+ Battery General Description The MAX1898, with an external PNP or PMOS transistor, forms a complete charger for 1-cell lithium-ion (Li+) batteries.
The MAX1898 provides accurate constant-current/constant-voltage charging.
Battery regulation voltage accuracy is ±0.
75% for optimum battery performance and cycle life.
Charging current is user set, but is sensed internally so no external current-sense resistor is needed.
The MAX1898 also provides outputs to monitor charge status, presence-of-input power source, and charge current.
Additional features include shutdown, optional charge-cycle restart without input-power cycling, selectable char...
