Table 2. LTC695-3.3 Reset Active Time and Watchdog Time-Out Selections
Push-Button Reset
The LTC694-3.3/LTC695-3.3 do not provide a logic input
for direct connection to a push-button. However, a push-
button in series with a 100
resistor connected to the
RESET output pin (Figure 13) provides an alternative for
manual reset. Connecting a 0.1
μ
F capacitor to the RESET
pin debounces the push-button input.
The 100
resistor in series with the push-button is
required to prevent the ringing, due to the capacitance and
lead inductance, from pulling the RESET pins of the MPU
and LTC69X below ground.
