Description
RST1
Output Open-drain reset output, active-low, no internal pull-up resistor.
RST2
Output Open-drain reset output, active-low, no internal pull-up resistor.
SR0
Input
Primary push-button Smart Reset™ input, active-low, fixed voltage input logic
levels, no internal pull-up.
SR1
Input
Secondary push-button Smart Reset™ input - combines with the primary push-
button reset to provide setup delay time, active-low, fixed voltage input logic
levels, no internal pull-up.
SRC Input
Smart Reset™ input delay setup control: connect to an external capacitor to
adjust the delay setup time (t
SRC
).
V
CC
Supply
Supply voltage input. Power supply for the device. A 0.1 µF decoupling ceramic
capacitor is recommended to be connected between V
CC
and V
SS
pins.
V
SS
Supply Supply ground.
NC No connect (not bonded); should be connected to V
