jännitteenvalvontapiiri
A jännitteenvalvontapiiri, or voltage monitoring circuit in English, is an electronic circuit designed to detect and signal when a voltage level falls below or rises above a predetermined threshold. These circuits are crucial for protecting sensitive electronic components and systems from damage caused by overvoltage or undervoltage conditions. They are commonly found in power supplies, battery management systems, automotive electronics, and industrial control systems.
The core function of a jännitteenvalvontapiiri is to compare the input voltage against a reference voltage.
There are various types of voltage monitoring circuits, including simple undervoltage lockout (UVLO) circuits, overvoltage protection
