MIC809/810
Microprocessor Reset Circuits General Description Features The MIC809 and MIC810 are inexpensive microprocessor
supervisory circuits that monitor power supplies in
microprocessor-based systems. Precision voltage monitor for 3V, 3.3V, or 5V power
supplies /RESET remains valid with VCC as low as 1.4V for
SOT-23 packaged part /RESET remains valid with VCC as low as 1V for
SC70-packaged part Typically less than 15Î¼A supply current for SOT-23
packaged part 5ÂµA (typical) supply current for SC70-packaged part 140ms (minimum) reset pulse widths available Available in 3-pin SOT-23 and SC-70 package 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 VCC 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, minimum).
