RESET
Active LOW reset.
RESET
is asserted if V
CC
falls below the reset threshold
and remains low for at least 140ms after V
CC
rises above the reset threshold.
Active HIGH reset. RESET is asserted if V
CC
falls below the reset
threshold and remains high for at least 140ms after V
CC
rises above
the reset threshold.

MR
Manual Reset Input. A logic LOW on
MR
asserts RESET. RESET remains
active as long as
MR
is LOW and for 140ms after
MR
returns HIGH. The
active low input has an internal 20k
pull-up resistor. The input should be left
open if not used.

Notes
1)
The “YM” in the SOT-143 package marking indicates the Year
and Month of production.
All NiPdAu devices will be marked to indicate product type and
package. Threshold and full part numbers will be provided on box
and reel labels as well as all Shipping documents.
