General description
The MAX809/MAX810 are single function microprocessor resets used to monitor supply voltages in microprocessor and other logic systems. They provide a reset signal
to the microprocessor during power-up, power-down, and brownout conditions. The reset signal is asserted when the supply voltage drops below the preset threshold, and
the signal is released a set time after the supply voltage has risen above the preset threshold.
The MAX809 has an active-LOW reset output while the MAX810 has an active-HIGH reset output.
The low supply current of typically 17 uA makes the MAX809/MAX810 ideal for use in portable, battery operated equipment. They are available in the 3-pin SOT23 and
SC70 packages.
