AUR9807 - Single-cell Li-Ion Charger IC

Description

The AUR9807 is a single-cell Li-ion charger IC with system power management feature.

It charges the battery and power the system simultaneously.

The maximum charging current (up to 1.5A) is set by external resistor for fast charging.

Features

  • QFN Package.
  • Active Power Management (APM) for Simultaneously Powering the System and Charging the Battery.
  • Total Current Supported Up to 2 Amperes (System Loading Having Higher Priority on the Budget).
  • Automatic Power Source Selection (AC Adapter or Battery).
  • 40mΩ Power Path for the Battery to Supply the System Power Efficiently.
  • Junction Temperature Detection and Thermal Regulation During Charging Process.
  • External LED Indicating.

NOT RECOMMENDED FOR NEW DESIGN Data Sheet Single-cell Li-Ion Charger IC with System Power Management AUR9807 General Description The AUR9807 is a single-cell Li-ion charger IC with system power management feature. It charges the battery and power the system simultaneously. The maximum charging current (up to 1.5A) is set by external resistor for fast charging. The output voltage for the system is regulated to a nominal value (three different versions available: 4.4V, 5V or 6V); the actual value of the output voltage depends on the input voltage from the adapter, the charging current and the system loading. With the decrease of the input voltage or the increase of the system loading current, the output voltage drops.
