However, when a current-limited adapter is used, the device works in Quasi Pulse Mode thanks to its low
input voltage. The device has an operating input voltage ranging from 2.5V to 14V. On the L6924D is
possible to select the output voltage (4.1V-4.2V) with ±1% voltage accuracy.
This allows to use both coke and graphite anode cells. The L6924D offers two open collector outputs, for
diagnostic purpose, which can be used to drive two external LEDs, or to communicate with a host
microcontroller.
Moreover, the voltage across the resistor connected between IEND and GND gives the status about the
charging current (working as a gas gauge) and some eventual faults, like battery over temperature, the
battery absence and the over time charge.
