Pushbutton Reset
The LTC692/LTC693 do not provide a logic input for direct
connection to a pushbutton. However, a pushbutton 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 pushbutton input.
The 100
resistor in series with the pushbutton is re-
quired to prevent the ringing, due to the capacitance and
lead inductance, from pulling the RESET pins of the MPU
and LTC692/LT693 below ground.
