MAXIM MAX809MEUR IC MPU/RESET CIRC SOT23-3, 3-Pin Microprocessor Reset Circuits
The MAX809/MAX810 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with or 3Vpowered circuits. These circuits perform a single function: They assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The only difference between the two devices is that the MAX809 has an active-low RESET output (which is guaranteed be in the correct state for V CC down to 1V), while the MAX810 has an active-high RESET output. The reset comparator is designed to ignore fast transients on VCC. Reset thresholds suitable for operation with a variety of supply voltages are available. Low supply current makes the MAX809/MAX810 ideal for use in portable equipment. The MAX809/MAX810 come 3-pin SOT23 package.
