MAX803, MAX809, & MAX810 MPU Reset Circuit ICs

Analog Devices MAX803, MAX809, and 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 with +5V, +3.3V, +3.0V, or +2.5V powered circuits. These circuits perform a single function. They assert a reset signal whenever the V_CC supply voltage declines below a preset threshold. This keeps it asserted for at least 140ms after V_CC 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 connected to a voltage higher than V_CC. The MAX803 and MAX809 have an active-low RESET output, while the MAX810 has an active-high RESET output.
