_______________General Desc ription
The MAX814/MAX815/MAX816 are high-accuracy
microprocessor (μP) supervisory circuits that provide
power-on reset, watchdog, and power-fail functions.
They eliminate manual trimming and improve reliability
in critical applications needing high-accuracy reset
thresholds. The RESET output is guaranteed to be in
the correct state for V
CC
down to 1V. The reset com-
parator is designed to ignore fast transients on V
CC
.
Reset thresholds are available for operation with a vari-
ety of 3V and 5V supply voltages.
A 75μA maximum supply current makes the MAX814/
MAX815/MAX816 ideal for use in portable equipment.
All three devices are available in 8-pin DIP and SO
packages. See the Selector Table below for a review of
features.
