MAX1898 - Linear Charger for Single-Cell Li Battery

Maxim

Datasheet Details

The MAX1898, with an external PNP or PMOS transistor, forms a complete charger for 1-cell lithium-ion (Li+) batteries..

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 all Li+ battery chemistries. The battery regulation voltage is 4.2V for the MAX1898EUB42 and 4.1V for the M.
