Battery Charger IC SL1056A

SiliconLake SL1056A is a Lithium-Ion or Lithium-Polymer dual cell linear battery charger which is designed for compact and cost-sensitive handheld devices. It combines charge status indication, charge termination, battery temperature monitoring, and high accuracy current and voltage regulation in a MSOP8 or SOP8 package.
The SL1056A charges the battery in three modes, precharge, constant current, constant voltage. If the battery voltage is below the precharge threshold VO(MIN), the SL1056A precharges the battery with a lower conditioning current. After precharge, the SL1056A applies a constant current to the battery. An external senseresister sets the charge current. The constant voltage mode continues until the battery reaches the regulation voltage.The battery temperature is continuously measured by an external thermistor through the TS pin. The SL1056A inhibits charge until the temperature is within the range
defined by users.
