On-Board Battery Charging Solution with NCP1851FCCT1G The NCP1851FCCT1G is an on-board single cell Li-Ion/Li-Polymer battery charger, ideal for a wide range of applications including consumer, power tools, toys, industrial and automotive. The NCP1851FCCT1G provides a complete, cost effective solution for charging single-cell Li-Ion or Li-Polymer batteries, reducing the time and complexity for development of the total solution. Features The most prominent characteristics of NCP1851FCCT1G include: • Automatic State-of-Charge (SoC) detection • Wide input voltage range from 4.5V to 30V • Automatically switching between the two input power supplies • Tight current loop with low oscillation • Up to 1A programmable output current with current foldback • Up to 4.2V programmable output voltage • Efficient LED driver providing up to 8 LEDs indication • Soft-Start/Soft-Stop transition Profiles • Output Over Voltage/Short Circuit protection • ODCP over current protection • Temperature monitor with thermal shut down • Automatic battery temperature compensation • Tiny SOP-8 package Application Fields and Working Principle The NCP1851FCCT1G from ON Semiconductor is a low power, cost effective solution for applications which are in need of an on-board charger for single-cell Lithium Ion/Polymer batteries. It can be used in applications such as consumer electronics, portable power tools, automotive, as well as industrial and medical applications. The battery charger highlights temperature monitoring and thermal shut down, soft-start/stop transition profiles, and output over voltage/short circuit protections. The NCP1851FCCT1G provides state-of-charge monitoring with automatic switching between two power supplies. It features 8 LEDs indication and a programmable output current up to 1A with a folded current loop that provides low oscillation. It also has a programmable output voltage of up to 4.2V, which can be configured depending on the battery type. The working principle of the NCP1851FCCT1G involves an AC-DC converter which takes in and converts AC input voltage into a DC output. This DC output is then provided as an input to the DC to DC converter, which converts it into the required input voltage for battery charging. This DC to DC converter then feeds the charger circuit for charging the battery. The charger circuit then regulates and monitors the battery charging process, protecting it from over voltage/short circuit, over current and temperature. Conclusion The NCP1851FCCT1G is a cost-effective and complete charging solution for a wide range of applications, from consumer electronics to automotive. The product simplifies design by providing a complete and tight looped current with low oscillation up to 1A programmable output current, over voltage/short circuit protection, an LED driver capable of providing up to 8 LED indication and an intelligent temperature monitoring and control system with an automatic battery temperature compensation module. All these features make the NCP1851FCCT1G a perfect choice for an on-board single-cell Li-Ion/Li-Polymer battery charging applications.
