Product Summary
The SC8011/B is a fully integrated, single cell, constant-cur-rent/constant-voltage Lithium-Ion\Li-Polymer battery charger management system. The SC8011/B has built in intelligence and extreme functionality. When the battery voltage is below 2.8V the charger operates in a precharge mode with a charging current of up to 125mA based on the ITERM pin resistor. The applications of the SC8011/B include Cellular phones, PDA’s and Handheld computers, Handheld meters, Charging stations, Digital cameras.
