MAX811, MAX812

4-Pin µP Reset Monitors

The MAX811 and MAX812 are cost–effective system supervisor

circuits designed to monitor V in digital systems and provide a reset

signal to the host processor when necessary. A manual reset input is

provided to override the reset monitor, and is suitable for use as a

push–button reset. No external components are required.

The reset output is driven active within 20 µsec (4 µsec for

F version) of V falling through the reset voltage threshold. RESET

is maintained active for a minimum of 140 msec after V rises above

the reset threshold. The MAX812 has an active–high RESET output

while the MAX811 has an active–low RESET output. The output of

SOT–143

CASE 318A

the MAX811 is guaranteed valid down to V = 1 V. Both devices are

available in a 4–Pin SOT–143 package.

The MAX811/12 are optimized to reject fast transient glitches on

the V line. Low supply current of 7 µA (V = 3.3 V) makes these

devices suitable for battery powered applications.
