Lithium-ion (Li-Ion) and lead-acid batteries require extremely accurate charging current and output voltages to optimize battery life and performance. To address this need, we have battery Sensor ICs, battery cell controller ICs and battery charger ICs designed to provide the industry's highest performance and accuracy, as well as exceptional configuration flexibility.

NXP's battery charger ICs offer output voltage accuracy of +/-0.4 percent over temperature and charging current accuracy of +/-5 percent over temperature. The ICs can be customized to create hundreds of configurations to address a wide range of portable and ultramobile device needs. A designer can select features and specifications, such as pin-out, feature set, charging parameters and LED indication, and NXP can deliver customized charger ICs by programming them at the end of the manufacturing process.
