Li-ion charger with integrated fault protection
The MIC79110YML-TR from Microchip is a linear Li-ion battery charger IC in a 10-MLF package (3x3 mm). It delivers a programmable charge current up to 1.2 A from a supply rail rated to 16 V, making it a compact fit for portable and industrial equipment that needs a single-cell Li-ion charge solution. Three on-chip fault protections — over-current, over-temperature, and reverse-current — cover the common failure modes in battery charging without external supervisory components.
