NCP1835MN24T2

The NCP1835MN24T2 is a versatile integrated linear charger designed for 1-cell Li-ion batteries. With its constant current, constant voltage (CCCV) profile, it can charge at currents of up to 1.0 A. Its low input voltage capability, adjustable charge current, and onboard thermal foldback make it suitable for a variety of wall adapters. It offers the flexibility to charge from a standard voltage-source wall adapter as a CCCV charger or from a current-limited adapter to limit power dissipation in the pass device. Additionally, the NCP1835 can maintain regulation without a battery, providing added convenience and functionality
