MP111 - Dying Gasp Storage and Release Controller

General Description

The MP111 is a dying gasp storage and release controller.

It charges storage capacitor from the input during normal operation.

Once the storage capacitor is charged to the selected voltage, the charge is stopped, and the storage capacitor is separated from the input.

Key Features

  • Wide 4.5V to 18V Input Operating Range.
  • 2.5A dumping current from Storage to VIN.
  • Built-in 250mA Current Limit for Charging Storage Capacitor.
  • User Programmable Storage and Release Voltage.
  • Dying Gasp FLAG Indicator.
  • Available in SOIC-8 package.

The Future of Analog IC Technology MP111 Dying Gasp Storage and Release Control IC DESCRIPTION The MP111 is a dying gasp storage and release controller. It charges storage capacitor from the input during normal operation. Once the storage capacitor is charged to the selected voltage, the charge is stopped, and the storage capacitor is separated from the input. The charging circuit maintains the storage voltage after the charge is completed. The MP111 keeps monitoring the input voltage, and releases the charge from storage capacitor to input capacitor when the input voltage is lower than the selected release voltage. It regulates the input voltage to keep it close to release voltage for as long as possible.
