Remaining Battery Power Display
Monolithic IC MM1206
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.
Features
1. There are three displays for remaining battery power :
FULL / MIDDLE / EMPTY.
2. Nine patterns built in for detection voltage, linked to two manganese batteries.
Standard setting : 2.5V, 2.25V
3. External parts held to a minimum
