MAX809 Datasheet (NXP) - 3-pin microprocessor resets

MAX809, 3-pin microprocessor resets

The MAX809/MAX810 are single function microprocessor resets used to monitor supply voltages in microprocessor and other logic systems.

They provide a reset signal to the microprocessor during power-up, power-down, and brownout conditions.

The reset signal is asserted when the supply voltage drops be
