APPLICATION NOTE 2769
Dual Comparator Thermally Protects Li+
Battery

A dual comparator and thermistor set safe temperature limits for a lithium-ion battery charging circuit. The
single-cell lithium-ion (Li+) battery charger can be powered from a USB port or external supply.


Most manufacturers recommend that Li+ (lithium-ion) batteries not be charged below 0°C or above +50°C. You
can monitor both of these limits by adding a thermistor and dual (window) comparator to a Li+ battery charger
(Figure 1).
