NCP1800DM42R2 Description

Short technical summary and product information.

The NCP1800DM42R2 is a single-cell Lithium Ion battery charge controller designed by ON Semiconductor. This device operates as a constant current, constant voltage (CCCV) charger, allowing the external sense resistor to set the full charging current. The termination current is precisely controlled at 10% of the full-charge current, and the voltage is regulated to within ±1% during the final charge stage.

 

Key features include integrated voltage and programmable current regulation, cell conditioning for deeply discharged cells, and end-of-charge detection. It offers a charger status output for LED or host processor interface, a charge interrupt input, and safety shutoff for battery removal. The device also includes input over and undervoltage lockout for robust operation.

 

This charge controller is suitable for applications such as cellular phones, PDAs, handheld equipment, and other battery-operated portable devices. It comes in an 8-MSOP package and is designed for surface mount installation. The operating temperature range is -20°C to 85°C (TA).
