hengjiaxing HX811T

The HX811X 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 can provide a reset signal to the system during power-up, power-down, and power-saving conditions, or when the supply voltage falls below the preset threshold voltage Vth. Meanwhile, when power is applied or the supply voltage recovers above the preset threshold voltage Vth, or when the enable pin MR transitions from low to high, the VRESET output will go high after a delay of Trp. When the input voltage of the HX811X series falls below the threshold voltage Vth, the VRESET output is driven low; when the enable control pin MR is low, the VRESET output is also driven low. Simple to use with no external components required.
