CircuitLow Battery Voltage Indicator by IC 8211
This be Low Battery Voltage Indicator circuit, model easily. It can show the level voltage , minimum of battery get with LED. By use IC number IC 8211 or ICL 8211 (Programmable Voltage Detectors) when voltage of power supply lower arrive at the dot that fix ( but do not lower 1.15V). The Voltage Comparator circuit within IC 8211 as a result will order give the circuit gives current come out drive LED1 stick bright get. This circuit uses current altogether about 7mA only and can set voltage minimum get with VR1. Besides still use a little equipment 4 pcs. can work already. You see the detail in the circuit.
