Processor Supervisor 4.75V 3V/3.3V/5V 3-Pin SOT-23 T/R

The MIC809 are inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor-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. 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 comes in a 3-pin SOT-23 and SC-70 package. The MIC809 is also available with a shorter reset timeout (30ms, minimum). 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 15µA supply current for SOT-23 packaged part 5µA (typical) supply current for SC70-packaged part 140ms (minimum) reset pulse widths available Available in 3-pin SOT-23 and SC-70 package
