Pin descriptions
See Figure 2 and Table 2 for a brief overview of the signals connected to this device.
Active-low RST output (push-pull)
Pulses low when VCC drops below VRST, and stays low as long as VCC is below the reset
threshold. It remains low for trec after VCC rises above the reset threshold.
Active-low RST output (open drain)
Pulses low when VCC drops below VRST, and stays low as long as VCC is below the reset
threshold. It remains low for trec after VCC rises above the reset threshold. RST output has
an internal 5.5 kΩ pull-up resistor.
