The MAX803TEXR is a microprocessor (mP) supervisory circuit used to monitor the power supplies in mP and digital systems. MAX803TEXR provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered or 3V-powered circuits.
This circuit MAX803TEXR performs a single function. It asserts a reset signal whenever the VCC supply voltage declines below the preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The MAX803TEXR has an open-drain output stage. The open-drain /Reset ouput require a pull-up resistor than can be connected to VCC. 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 MAX803TEXR ideal for use in portable equipment. This device comes in a 3-pin SC-70 package.
