www.DataSheet4U.com MITSUMI Remaining Battery Power Display MM1206 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 Package SOP-8D (MM1206XF) VSOP-8A (MM1206AF) Detection Voltage Matrix Chart SW1 GND GND GND OPEN OPEN OPEN VCC VCC VCC SW2 GND OPEN VCC GND OPEN VCC GND OPEN VCC Detection Voltage 1 Detection Voltage 2 2.64V 2.62V 2.60V 2.52V 2.50V 2.48V 2.42V 2.40V 2.38V 2.35V 2.27V 2.18V 2.35V 2.25V 2.17V 2.30V 2.24V 2.15V Voltage Accuracy * Detection Voltage 1 : ±100mV typ.
