Advanced Lithium-Ion Linear Battery Charger LN9501 ■ General Description The LN9501 is a single Lithium-Ion or Lithium-Polymer 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 MSOP-8 package.
The LN9501 charges the battery in three modes, precharge, constant current, constant voltage.
If the battery voltage is below the precharge threshold VO(MIN), the LN9501 precharges the battery with a lower conditioning current.
After precharge, the LN9501 applies a constant current to the battery.
