What is a Voltage Detector?
A voltage detector is a device that monitors and manages the voltage applied inside electronic equipment. It is capable of monitoring and detecting when the voltage falls below a voltage threshold set for each device or when voltage exceeds a certain level and is indispensable for the safe use of electronic equipment.
It can prevent electronic equipment from malfunctioning, etc., in advance by issuing a power-on reset signal or a reset signal to avoid the CPU in the electronic equipment from running out of control when an abnormality is detected.
Applications of Voltage Detectors
Voltage detectors are installed in all kinds of electronic devices and are also used in familiar electronic devices (PCs, smart phones, car navigation systems).
Most electronic devices contain microcontrollers (MCUs). If a microcontroller is supplied with a voltage below the minimum operating voltage or if the power supply voltage is unstable, the microcontroller may malfunction, causing other parts of the electronic equipment to malfunction or break down.
Principle of Voltage Detectors
Voltage detectors can be used in various ways, not only for the safe activation of microcontrollers.
One is to extend the usage time of batteries and cell batteries. As the remaining battery charge decreases, the voltage of the battery becomes weaker and falls below the minimum operating voltage of the electronic equipment, resulting in malfunction or failure of the microcontroller or electronic equipment.
In order to prevent this from happening, it is possible to control the operation of electronic equipment by issuing a reset signal before the battery voltage suddenly drops.
In addition, the use of a more accurate detection voltage can prolong the battery life.
Some microcontrollers have a built-in reset function, but in the case of large electronic equipment such as in-vehicle equipment and industrial equipment, this function alone is not safe, and a voltage detector may be used in combination with the reset function.
In the case of automotive equipment, voltage detectors are used to monitor and detect overvoltages.
Suppose a voltage detector is used in combination with an overvoltage detector as an independent mechanism from the microcontroller. In that case, it can detect overvoltages more accurately and safely, preventing equipment malfunctions and failures.
