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 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.)

1.1.2

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 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 trec after MR returns to high. This active-low input has an internal 50 kΩ pull-up resistor to
