HGSEMI MAX811TM4-3.08/TR

The MAX811x series is a microprocessor reset IC with voltage detection function and enable control pin, designed to monitor the supply voltage of microcontrollers or other logic systems. It provides a reset signal to the system during power-up, power-down, and power-saving conditions, or when the supply voltage falls below the preset detection threshold Vth. When the supply voltage rises above the preset detection threshold Vth during power-up or voltage recovery, or when the enable pin transitions from low to high, the output will go high after a delay of Trp. When the input voltage falls below the detection threshold Vth, the output is low; when the enable control pin voltage is low, the output is also low. Simple to use with no external components required.
