Description
• The MAX6333 and 6332 are system supervisor
circuits designed to monitor V in digital systems

• To prevent jitter, the reset threshold voltage has a
built-in hysteresis of 0.4% of V

• The MAX6333 has an active-low reset output,
while the MAX6332 has an active-high reset
output. Both devices have push/pull output drives.

• Low supply current of 3µA makes these devices
well suited for battery powered applications. They
are designed to reject fast transients from causing

These devices have a certain immunity to fast negative
going transients. The graph titled “Transient Rejection”
shows the maximum allowable transient amplitude and
duration to avoid triggering an unintended reset. As
shown in the graph shorter transients can have larger
amplitudes without triggering resets.
