NCP1852A - Fully Integrated Li-Ion Switching Battery Charger

Download the NCP1852A datasheet PDF. This datasheet also covers the NCP1852 variant, as both devices belong to the same fully integrated li-ion switching battery charger family and are provided as variant models within a single manufacturer datasheet.

Description

Battery Charger Input.

These two pins must be decoupled by at least 1 mF capacitor and connected together.

System Power Monitor input.

Features

  • under software supervision. An optional battery FET can be placed between the system and the battery in order to isolate and supply the system. The NCP1852 junction temperature and battery temperature are monitored during charge cycle, and both current and voltage can be modified accordingly through I2C setting. The charger activity and status are reported through a dedicated pin to the system. The input pin is protected against overvoltages. The NCP1852 also provides USB OTG support by boosting.

NCP1852, NCP1852A Fully Integrated Li-Ion Switching Battery Charger with Power Path Management and USB On-The-Go Support The NCP1852 is a fully programmable single cell Lithium−ion switching battery charger optimized for charging from a USB compliant input supply and AC adaptor power source. The device integrates a synchronous PWM controller, power MOSFETs, and the entire charge cycle monitoring including safety features under software supervision. An optional battery FET can be placed between the system and the battery in order to isolate and supply the system. The NCP1852 junction temperature and battery temperature are monitored during charge cycle, and both current and voltage can be modified accordingly through I2C setting.
