MP111 Dying Gasp Storage and Release Control IC The Future of Analog IC Technology DESCRIPTION FEATURES The MP111 is a dying gasp storage and release Wide 4.5V to 18V Input Operating Range controller. It charges storage capacitor from the 2.5A dumping current from Storage to VIN input during normal operation. Once the storage Built-in 250mA Current Limit for Charging capacitor is charged to the selected voltage, the Storage Capacitor charge is stopped, and the storage capacitor is User Programmable Storage and Release separated from the input. The charging circuit Voltage maintains the storage voltage after the charge Dying Gasp FLAG Indicator is completed. Available in SOIC-8 package The MP111 keeps monitoring the input voltage, APPLICATIONS and releases the charge from storage capacitor Cable/DSL/PON Modems to input capacitor when the input voltage is lower than the selected release voltage. It Home Gateway regulates the input voltage to keep it close to Access Point Networks release voltage for as long as possible. All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality The MP111 has built-in current limit circuit Assurance. MPS and The Future of Analog IC Technology are Registered during the charging up of the storage capacitors. Trademarks of Monolithic Power Systems, Inc. The storage and release voltage can be programmed to users desired value by external resistors. The MP111 comes in an SOIC-8 package and requires a minimum number of readily available standard external components.
