Outline
This IC detects battery voltage and displays the remaining power on an LED or LCD display. The appeal of battery-driven equipment lies in its portability, but when the battery runs down and the equipment does not function, customer complaints and breakdowns may result.
This IC prevents such trouble before it starts.
