Overview
The HG811x series is a microprocessor reset IC with voltage detection functionality and an 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 voltage Vth. When the supply voltage rises above Vth during power-up or 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 Vth, the output of the HG811x series goes low; the output also goes low when the enable control pin voltage is low. Simple to use with no external components required.
