MAX803TEXR+T

The MAX803TEXR+T is a 3-pin microprocessor Reset Circuit for intelligent instruments. The MAX803 is 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. These circuits perform a single functions of 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. Reset thresholds suitable for operation with a variety of supply voltages are available. The MAX803 has an open-drain output stage. The MAX803's open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The reset comparator is designed to ignore fast transients on VCC and the outputs are guaranteed to be in the correct logic state for VCC down to 1V.

• Fully specified over-temperature
• 12µA Supply current
• Guaranteed reset valid to VCC = +1V
• Power supply transient immunity
• No external components
