Summary description
Pin Descriptions
Active-Low, Push-pull Reset Output (RST) - STM6718/20/78/80
The RST pin is driven low and stays low whenever VCC1 or VCC2 or RSTIN falls below its
factory-trimmed or adjustable reset threshold or when MR goes to logic low. It remains low
for trec after ALL supply voltages being monitored rise above their reset thresholds and MR
goes from low to high. (Push-pull outputs are referenced to VCC1.)
Active-Low, Open Drain Reset Output (RST) - STM6717/19/77/79
The RST pin is driven low and stays low whenever VCC1 or VCC2 or RSTIN falls below its
factory-trimmed or adjustable reset threshold or when MR goes to logic low. It remains low
for trec 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 VCC1. A 10kΩ pull-up resistor
should be sufficient for most applications.
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 trec after MR returns to high. This active-low input has an internal 50kΩ pull-up resistor to
