Power-On Reset
If the power supply voltage goes below the POR trip
voltage (V
< V
1.7V), the internal POR circuit
DD
POR
will reset all of the internal registers to their power-up
defaults (this is a protection against low power supply
voltages). The POR circuit also holds the part in shut-
down mode while it is activated. It temporarily overrides
the software shutdown status. The POR releases the
shutdown circuitry once it is released (V
> V
).
DD
POR
A 0.1 µF bypass capacitor mounted as close as possi-
ble to the V
pin provides additional transient
DD
immunity.
