Working Principles

The MAX6450UT16L+T is a voltage supervisor IC that continuously monitors the supply voltage of a system. It compares the voltage level with a pre-set threshold and generates a reset signal when the voltage falls below this threshold. The device also includes a manual reset input, allowing the system to be reset immediately if required.

The IC operates with a low quiescent current, making it suitable for battery-powered applications. It offers multiple threshold voltage options, enabling designers to select the appropriate voltage level for their specific requirements. Additionally, the power-on reset timeout feature prevents false resets during power-up by delaying the generation of the reset signal for a specified period.
