TDSEMIC IMP811R-TD

This device is a microprocessor reset IC with enable control, featuring voltage detection for monitoring the supply voltage of microcontrollers or other logic systems. It provides a reset signal to the system during power-up, power-down, power-saving mode, or when the supply voltage drops below the preset detection threshold Vth. When power-up is complete or the supply voltage recovers above Vth, or when the enable control pin voltage transitions from low to high, the output goes high after a delay of Trp. If the input voltage falls below Vth, or the enable control pin MR is low, the output remains low. This device is easy to use and requires no external components.
