Engineers are resorting to using low-power circuits to continually monitor the vital functions of the system. When an event occurs, these circuits flag the micro (usually in the form of interrupts) to ...

The circuit in Figure 1 monitors the voltage of a single lithium-ion cell that connects in series in a battery. The circuit communicates with a supervisor processor. The supervisor monitors all cells ...

In a basic implementation of the power-monitor circuit (Fig. 1), current passes from source to load through the current-sense resistor R1. In conjunction with R1, U1 provides an output voltage ...

2. The detailed circuit uses five standard transistors plus passive components to implement the one-pin battery-monitor solution. When the microcontroller decides it needs to know the battery ...

Ingersoll Rand Security Technologies' UL294-listed power supplies include the 500-ULAC 1-Amp and 3-Amp power supplies. Supplied standard with AC input, output and battery monitoring circuits and ...

These devices come with an integrated battery voltage monitor to make it possible to measure the remaining charge left in the battery. The additional battery monitor circuit is one of the key features ...
