com Micrel MIC809-5 Microprocessor Reset Circuit General Description The MIC809-5 is a power supply supervisor that provides under-voltage monitoring and power-on reset generation in an industry standard 3-pin SOT package and SC-70 package.
The reset output is asserted at power-on and any time the input voltage drops below the programmed threshold.
It remains asserted for 30ms (min.
) after the input subsequently rises back above the threshold boundary.
The MIC809-5 has an active-low reset output.
The MIC809-5 is inherently immune to brief power supply transients.
Typical supply current is a low 5µA.
For those applications that require a manual reset function, see the MIC811/812.
For those applications that require a longer reset timeout, see the MIC809/810.
(The MIC809-5 is identical to the industry-standard MIC809 with the exception of a shorter reset timeout).
