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 charge termination safety timer, and low-current preconditioning for deeply discharged cells. The MAX1898 offers the maximum integration and functionality in the smallest, most basic application circuit possible. Very few external components are required. The MAX1898 offers two versions to safely charge
