This is a 1.2 – 12 V, max 1A power supply with a low voltage indicator LED. The indicator part includes three diodes and one LED. For example you are charging a battery, you can observe the charge ...

Even today much logic is still powered from 5 volts and it then seems obvious to power the circuit using a standard regulator from a rectangular 9-V battery. A dis-advantage of this approach is that ...

The following circuit uses a low-power CMOS comparator and an LED to indicate low-battery voltage without causing excessive current drain. To view the application note, click on the URL below. Circuit ...

AVTs help reduce the risk of exposure to electrical hazards and improve worker safety by automating and simplifying the process of verifying the absence of voltage. The importance of creating a safe ...
