    The task is to create a circuit for LTC1980 IC which would allow the charger to operate even when the under-voltage lockout occurs. This IC has a specific timer that stops the charger if under-voltage of the battery is present longer then specified time. This is from datasheet: "During trickle charging, if the battery voltage remains below 2.7V for
