MAX803LEXR/V+T Information

MAX803/MAX809/MAX810 MPU Reset Circuit ICs

Maxim MAX803/MAX809/MAX810 Microprocessor Reset Circuit ICs are used to monitor the 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 +5V, +3.3V, +3.0V, or +2.5V powered circuits. These circuits perform a single function. They assert a reset signal whenever the VCC supply voltage declines below a preset threshold. This keeps 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, while the MAX809/MAX810 have push-pull outputs. The MAX803's open-drain active-low RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The MAX803/MAX809 have an active-low RESET output, while the MAX810 has an active-high RESET output.Learn More
