Working Principles

The MAX16033LLB23+T is designed to monitor the supply voltage of an electronic system. It compares the input voltage with a user-defined threshold voltage. When the supply voltage falls below the threshold, the device asserts the reset signal, indicating a power failure or low voltage condition. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

The manual reset input allows the system to be reset immediately, overriding the voltage monitoring function. The open-drain reset output can be connected to external circuitry for monitoring purposes or cascading multiple devices.
