A new product that can perform both voltage drop detection and overvoltage detection in one device!! Fail-safe functionality can be enhanced!!
This product can detect both voltage rise and fall with just one unit, enhancing the voltage monitoring function. Standard reset ICs typically only monitor one side (either overvoltage or undervoltage) and are referred to as single-type, but this product allows for monitoring on both sides, enabling it to perform two roles with a single unit. This product has two built-in comparators, each detecting voltage rise and fall. The comparators are designed with hysteresis to prevent malfunction due to chatter. Additionally, the outputs of the comparators are independent, allowing for individual output retrieval. However, since the output format is open collector, it can also be used as a wired OR through external connections.
