Watchdog Input
(MAX6358/MAX6359/MAX6360)
The MAX6358/MAX6359/MAX6360 include a WDI to
provide a reset if the P goes into an infinite loop. After
a reset, the start-up timeout period and the initial time-
out period is nominally 46.4sec to allow the P time to
initialize. After the first transition on the WDI and after
any toggle of the watchdog thereafter, the timeout peri-
od is nominally 2.9sec.
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 3. Note that this configuration does
not work for the open-drain outputs of the MAX6352/
MAX6355/MAX6358.
Monitoring a Negative Voltage
To monitor a negative supply rail using RSTIN or the
MAX6355/MAX6356/MAX6357, use the circuit shown in
Figure 4. In this configuration, a reset is issued when
the negative supply falls below VINTH.
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.
