MXD1810–MXD1813/ MXD1815–MXD1818 Low-Power μP Reset Circuits in 3-Pin SC70/SOT23 General Description The MXD1810–MXD1813/MXD1815–MXD1818 family of microprocessor (μP) reset circuits monitor power supplies in μP and digital systems. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +2.5V/+3.0V/+3.3V (MXD1815–MXD1818), and +5V (MXD1810–MXD1813) systems. These circuits assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping reset asserted for at least 100ms after VCC rises above the reset threshold. The MXD1813/MXD1818 also keep reset asserted for at least 100ms after the output is momentarily pulled to GND by an external pushbutton switch.
