Answer: Low Voltage Detect is used to monitor the device voltage. The power source is normally a battery that ramps down slowly. This means that the LVD circuity can be disabled for most of the time, and only enabled occasionally to do the device voltage check. Question 3: Should I enable the BOR circuit for a battery powered application? Answer: The BOR circuit is intended

So change the 10 K variable resistor circuit to warn until the battery hits that amount or set the warning circuit when the battery hits
This 555 low voltage indicator circuit is designed to activate an LED when the power supply voltage exceeds a specific threshold and to make it flash when the batteries require replacement. The provided component values are optimized for a 9 V operation.
I was looking to see if there is a low voltage detection circuit that could be made without ICs. I found this circuit but with the given values and configuration I don''t understand how it could work. What keeps the LED transistor from conducting first having the lower resistance to its base? Wouldn''t the 33-47 kΩ voltage divider only turn off
12V Low Voltage Battery Indicator Circuit. This circuit will alarm when the battery voltage gets lower than 12.4V. We want to use a 12V 8A water pump (2000GRH Model) in the garden which has no AC electricity. So, we will use a 12V 45Ah Lead-acid battery instead.

There are many ways to make one, you can use a 741 IC, 555 IC, 8211 IC or a SCR, but here we will learn how to make one using a transistor. The basic principle is that we use the transistor as a switch i.e the transistor flips between the ON and OFF position
implementation is ACTIVE LOW. So when the battery voltage drops below 2.0V, the comparator output goes low, providing as an alert signal to whatever device is monitoring the output. Hysteresis is integrated in the comparator such that the comparator output will return to a logic high state when the battery voltage rises above 2.034V. This circuit utilizes an open-drain

$begingroup$ I''m measuring the battery level of a li-po battery. The goal of the circuit is to turn the LED on when the level of the battery drops below 3 V. Currently, LED turns on above the set low battery voltage level, 3V, which is not the desired performance. It should be off in the 4.2V-3.1V range and turn on at 3V and below. $endgroup$

If V is the voltage at which you want the LED to indicate low battery, then, 1.42*V=1+ (R1/R2) Choose appropriate values of R1 and R2. Once you have calculated the values of the two resistors you can go ahead and set up the circuit. I designed this indicator for a robot i'm working on so the 5V comes from the microcontroller (Arduino) output.
