    Microprocessor Reset Circuit General Description Features The MIC1810 is an inexpensive microprocessor supervisory
    circuit that monitors power supplies in microprocessor based
    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
    5%, 10%, or 15% drop in 5V powered systems.
    The MIC1810 has an active low /RESET output. The reset
    output is guaranteed to remain asserted for a minimum of
    100ms after VCChas risen above the designated reset threshold level. The MIC1810 comes in a 3-pin SOT-23 package. Precision voltage monitor for 5%, 10%, or 15% drop in
    5V power supplies /RESET remains valid with VCC as low as 1V 5µA supply current (typical) 100ms minimum reset pulse width No external components required Available in 3-pin SOT-23 package Ordering Information Applications Portable equipment
