1.2 Pin descriptions
See Figure 1 and Ta bl e 2 for a brief overview of the signals connected to this device.
1.2.1 Active-low RST output (push-pull)
Pulses low when V
CC
drops below V
RST
, and stays low as long as V
CC
is below the reset
threshold. It remains low for t
rec
after V
CC
rises above the reset threshold.
1.2.2 Active-low RST output (open-drain)
Pulses low when V
CC
drops below V
RST
, and stays low as long as V
CC
is below the reset
threshold. It remains low for t
rec
after V
CC
rises above the reset threshold. RST output has
an internal 5.5 kΩ pull-up resistor.
