ON Launches NCP1800 Battery-Charge Controller
ON Semiconductor Corp. (Phoenix, AZ) introduced its new single-cell, lithium-ion, battery-charge controller that features a standby current of 0.5µA. Designed for use in a wide variety of portable electronic devices, the NCP1800 delivers a small footprint, reduced parts count and extended battery life for wireless and portable handheld products.
The NCP1800 is a constant-current/constant-voltage single-cell charge controller for use with either lithium-ion or lithium-polymer batteries. A conditioning and pre-charge phase helps protect and prolong the life of a nearly depleted lithium-ion battery by lightly charging it before the onset of full charge. The battery capacity and system safety are also maximized through the NCP1800's better than one-percent voltage regulation. Integrated voltage and programmable current features offer design versatility by providing various charging options for different lithium-ion battery chemistries and capacities. The NCP1800 accommodates either a PNP or PMOS transistor to control battery charging.
The NCP1800 is packaged in the space-saving Micro8. Pricing for the device is $0.83 per unit in 12,000-unit quantities.
