PoE power comes in the form of “48V at 350mA. If the PoE current is allowed to exceed 400mA, the standard calls for the PSE to break the circuit. This is a problem for devices that occasionally need a ...

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 ...

Fig 1. The ripple-eater design, essentially a filter with a follower, rejects as much as 40 dB in ripple and continues operating even as the supply voltage drops to low levels. Fig 2. With the ...
