Data Sheet 3-PIN MICROPROCESSOR RESET CIRCUITS AZ809/AZ810 The AZ809/810 microprocessor supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems. They provide a reset to the microprocessor in power-up, power-down and brownout conditions. The function of the AZ809/810 is to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factoryprogrammed reset threshold. The reset signal remains asserted for 240ms after VCC rises above the threshold. The AZ809 has an active-low RESET output, while the AZ810 has an active-high RESET output. Seven standard reset voltage options are available, suitable for monitoring 3.0V, 3.3V and 5.0V supply voltages. With a typical supply current of only 8uA when VCC is 3.3V, the AZ809/810 are ideal for use in portable equipment. These ICs are available in SOT-23 package. • Precise Monitoring of 3.0V, 3.3V and 5.0V Supply Voltages • Improved Maxim MAX809/MAX810 Replacement • 140ms Min.
