General Description
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 ±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 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 10-pin ultra-
thin μMAX package.
