Unused inputs
Connect unused monitor inputs to a supply voltage greater in magnitude than their specified
threshold voltages. For unused VxIN adjustable inputs connect a 1 M ohm resistor between
unused input and V2IN or (V
(device power supply pin). Do not connect unused monitor inputs to ground or allow them to
float.
Adding manual reset capability
Figure 8
Depressing the push button switch short circuits the analog input to ground and initiates a
RESET pulse. The switch must be open for at least 140 ms in order to de-assert the
RESET output. No external switch debounce is required. A small capacitor may be used to
improve noise immunity.

shows a circuit which can be used to add manual reset capability for the STM6710.
