3-pin microprocessor resets

9 October 2002 DSP, Micros & Memory

The MAX809/MAX810 from Philips Semiconductors are single function microprocessor resets, in 3-pin SOT23 package, 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. Low supply current of typically 17 µA makes them ideal for use in battery operated equipment.
