Additional Details

The SGM809-SXN3/TR 809S features a fixed threshold voltage, which is crucial for its monitoring function. The 'SXN3' likely refers to the specific threshold voltage level. It typically operates with a supply voltage range of 1.6V to 5.5V. The output is an active-low reset, which means that the reset signal is low when the voltage is below the threshold. It's commonly used with microcontrollers and microprocessors to ensure they start up and operate correctly even when the supply voltage fluctuates. The 'TR' suffix indicates that the part is supplied in tape and reel packaging for automated assembly.
