natlinear LN9501
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.| Part No. | LN9501 |

GENERAL DESCRIPTION
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. An external sense-resister sets the charge current. The constant voltagemode continues until the battery reaches the regulation voltage. The battery temperature is continuously measured by anexternal thermistor through the TS pin. The LN9501 inhibits charge until the temperature is within the range defined by users.●
