Description

MPU SUPERVISOR 5.5V SOT-143-4
The MAX811/MAX812 are low-power microprocessor (µP) supervisory circuits used to monitor power sup- plies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V- powered or 3V-powered circuits. The MAX811/MAX812 also provide a debounced manual reset input. These devices perform a single function: They assert a reset signal whenever the VCC supply voltage falls below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset thresh- old. The only difference between the two devices is that the MAX811 has an active-low RESET output (which is guaranteed to be in the correct state for VCC down to 1V), while the MAX812 has an active-high RESET out- put. The reset comparator is designed to ignore fast transients on VCC. Reset thresholds are available for operation with a variety of supply voltages. Low supply current makes the MAX811/MAX812 ideal for use in portable equipment. The devices come in a 4-pin SOT143 package.
