1.1 Pin descriptions
1.1.1 Active-low, push-pull reset output (RST) - STM6718/20/78/80
The RST pin is driven low and stays low whenever V
CC1
or V
CC2
or RSTIN falls below its
factory-trimmed or adjustable reset threshold or when MR
goes to logic low. It remains low
for t
rec
after ALL supply voltages being monitored rise above their reset thresholds and MR
goes from low to high. (Push-pull outputs are referenced to V
CC1
.)
1.1.2 Active-low, open drain reset output (RST) - STM6717/19/77/79
The RST pin is driven low and stays low whenever V
CC1
or V
CC2
or RSTIN falls below its
factory-trimmed or adjustable reset threshold or when MR
goes to logic low. It remains low
for t
rec
after ALL supply voltages being monitored rise above their reset thresholds and MR
goes from low to high. Connect an external pull-up resistor to V
CC1
. A 10 kΩ pull-up resistor
should be sufficient for most applications.
1.1.3 Push-button reset input (MR)
When MR goes low the RST output is driven low. RST remains low as long as MR is low and
for t
rec
after MR returns to high. This active-low input has an internal 50 kΩ pull-up resistor to
