MAXIM INTEGRATED / ANALOG DEVICES MAX6805US29D3T Microcontroller Reset Circuit
The MAX6805US29D3+T is a low-cost, energy-efficient microprocessor reset circuit housed in a compact 4-pin SOT-143 package. It monitors supply voltages from 1V to 5.5V, offering reliable reset signaling during power supply fluctuations or manual resets. The device asserts an active-low, open-drain RESET signal whenever the voltage falls below a set threshold or manual reset is pressed, maintaining reset for approximately 150ms after recovery or release. Its transient immunity and low power consumption make it ideal for space-conscious systems like computers, controllers, portable devices, and critical power management applications.
