MAX16056–MAX16059
125nA Supervisory Circuits with Capacitor-
Adjustable Reset and Watchdog Timeouts
General Description
The MAX16056–MAX16059 are ultra-low-current 125nA
(typ) microprocessor (μP) supervisory circuits that mon-
itor a single system supply voltage. These devices
assert an active-low reset signal whenever the V CC
supply voltage drops below the factory-trimmed reset
threshold, manual reset is pulled low, or the watchdog
timer runs out (MAX16056/MAX16058). The reset output
remains asserted for an adjustable reset timeout period
after V CC rises above the reset threshold. Factory-
trimmed reset threshold voltages are offered from
1.575V to 4.625V in approximately 100mV increments
(see Table 1).
These devices feature adjustable reset and watchdog
timeout using external capacitors. The MAX16056/
MAX16058 contain a watchdog timer with a watchdog
select input (WDS) that multiplies the watchdog timeout
period by 128. The MAX16057/MAX16059 do not have
the watchdog feature.
The MAX16056–MAX16059 are available in either push-
