The TPS***1 and TPS***9 devices (both referred to
as TPS**3x)
are ultralow current (**0 nA, typical), voltage supervisory
circuits that monitor a single voltage. Both devices initiate an
active-low reset signal whenever the VDD supply
voltage drops below the factory-trimmed reset threshold voltage.
The reset output remains low for **0 ms (typical) after the
VDD voltage
rises above the threshold voltage and hysteresis. These devices are
designed to ignore fast transients on the VDD pin. The TPS***1
device includes a manual reset input that
forces RESET low
when MR is
low.
