### Simple Circuit Schematic 12 V Battery Indicator using LM393

Eltronicschool. - When you confuse to make simple electronic circuit diagram battery indicator with 12 Volt, in here we will show you Simple Circuit Schematic 12 V Battery Indicator using LM393 that you can try to realize this circuit to indicate your battery charger 12 volt.

Circuit Schematic

 Figure 1.  Simple Circuit Schematic 12 V Battery Indicator using LM393 (Circuitstoday)

Component List
1. R1     = 1M
2. R2     = 2K2
3. R3     = 1 , 0.5 W
4. R4     = 10K
5. R5     = 1K
6. D1     = IN5819
7. D2     = LED
8. IC 1   = LM393

Description

According circuitstoday describe the Simple Circuit Schematic 12 V Battery Indicator using LM393 like in figure 1 above as follow:

This simple circuit can be used to monitor whether a battery is charging or not. The voltage comparator IC LM393 is the heart of this circuit. The LED D1 will remain ON whenever there is at least 25 milli ampere current flowing to the battery. This particular circuit is designed for a 12V battery with charging current less than 1A.By slightly modifying the component values, the charging current and voltage can be modified.
