• Manufacturer Part Number: MAX6443
• Description: ?P Reset Circuits with Long Manual Reset Setup Period
• Manufacturer: MAXIM [Maxim Integrated Products]

The area below the curves of the graph is the region in
which these devices typically do not generate a reset
pulse. This graph was generated using a falling pulse
applied to V
old (V
ed (reset threshold overdrive). As the magnitude of the
transient increases (V
threshold), the maximum allowable pulse width
decreases. Typically, a V
below the reset threshold and lasts 20µs or less does
not cause a reset pulse to be asserted.
