The LTC693 provides an additional output (Watchdog
Output, WDO) which goes low if the watchdog timer is
allowed to time out and remains low until set high by the
next transition on the WDI pin. WDO is also set high when
V
CC
falls below the reset voltage threshold or V
BATT
.
The LTC693 has two additonal pins OSC SEL and OSC IN,
which allow reset active time and watchdog time-out
period to be adjusted per Table 2. Several configurations
are shown in Figure 12.
OSC IN can be driven by an external clock signal or an
external capacitor can be connected between OSC IN and
GND when OSC SEL is forced low. In these configurations,
the nominal reset active time and watchdog time-out
period are determined by the number of clocks or set by
the formula in Table 2. When OSC SEL is high or floating,
the internal oscillator is enabled and the reset active time
is fixed at 140ms minimum. OSC IN selects between the
1 second and 70ms minimum normal watchdog time-out
periods. In both cases, the time-out period immediately
after a reset is at least 1 second.
