voltages are available. The MAX803 has an open-drain output stage, while the MAX809/MAX810 have push-pull outputs.
The MAX803’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than V
CC
.
The MAX803/MAX809 have an active-low RESET output, while the MAX810 has an active-high RESET output. The
reset comparator is designed to ignore fast transients on V
CC
, and the outputs are guaranteed to be in the correct logic state
for V
CC
down to 1V. Low supply current makes the MAX803/MAX809/MAX810 ideal for use in portable equipment. The
MAX803 is available in a 3-pin SC70 package, and the MAX809/MAX810 are available in 3-pin SC70 or SOT23
packages.
