MIC809/810
Microprocessor Reset Circuits
General Description
The MIC809 and MIC810 are inexpensive microprocessor
supervisory circuits that monitor power supplies in micro-
processor based systems.
The function of these devices is to assert a reset if the power
supply drops below a designated reset threshold level. Several
different reset threshold levels are available to accommodate
3V, 3.3V or 5V powered systems.
The MIC809 has an active-low /RESET output, while the
MIC810 offers an active-high RESET output. The reset output
is guaranteed to remain asserted for a minimum of 140ms
after V
CC
has risen above the designated reset threshold
level. Having a push-pull output stage, the MIC809/810 does
not require a pull-up resistor at the output. The MIC809/810
comes in a 3-pin SOT-23 and SC-70 package.
The MIC809 is also available with a shorter reset timeout
(30ms min.). See the MIC809-5.
