Linear Charger for Single-Cell Li+ Battery  
General Description  
Features  
The MAX1898, with an external PNP or PMOS transistor,  
forms a complete charger for 1-cell lithium-ion (Li+) bat-  
teries. The MAX1898 provides accurate constant-cur-  
rent/constant-voltage charging. Battery regulation voltage  
accuracy is ±±.ꢀ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 cur-  
rent. Additional features include shutdown, optional  
charge-cycle restart without input-power cycling, selec-  
table charge termination safety timer, and low-current  
preconditioning for deeply discharged cells.

The MAX1898 offers the maximum integration and func-  
tionality 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  
MAX1898EUB41. Both are available in a 1±-pin ultra-  
thin µMAX package.
