MIC809-5
General Description
MIC809-5
Microprocessor Reset Circuit
Features
Micrel
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 pack-
age. 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.

Rejects brief input transients
Industry standard package and pinout
3-pin IttyBitty? SOT23-3 package and SC-70 package
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 identi-
cal to the industry-standard MIC809 with the exception of a
shorter reset timeout).
