Dual/Triple-Voltage
P Supervisory Circuits

_______________________________________________________________________________________
During the normal operating mode, the supervisor will
issue a reset pulse for the reset timeout period (140ms
min) if the P does not update the WDI with a valid tran-
sition (HIGH to LOW or LOW to HIGH) within the stan-
dard timeout period (1.6s min).
After each reset event (VCC power-up, manual reset, or
watchdog reset), there is an initial watchdog startup
timeout period of 25.6s. The startup mode provides an
extended period for the system to power up and fully
initialize all P and system components before assum-
ing responsibility for routine watchdog updates. The
normal watchdog timeout period (1.6s min) begins at
the conclusion of the startup timeout period or after the
first transition on WDI before the conclusion of the start-
up period (Figure 3).
Applications Information
Ensuring a Valid RESET Output
Down to VCC = 0
In some systems, it is necessary to ensure a valid reset
even if VCC falls to 0. In these applications, use the cir-
cuit shown in Figure 4. Note that this configuration does
not work for the open-drain outputs of the MAX6352/
MAX6355/MAX6358.
Interfacing to Ps with
Bidirectional Reset Pins
Microprocessors with bidirectional reset pins will con-
tend with the push-pull outputs of these devices. To
prevent this, connect a 4.7k
resistor between RESET
and the P’s reset I/O port, as shown in Figure 5. Buffer
RESET as shown in the figure if this reset is used by
other components in the system.
