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 (tSRC).

VCC

Supply

Supply voltage input. Power supply for the device. A 0.1 µF decoupling ceramic

capacitor is recommended to be connected between VCC and VSS pins.

VSS

Supply

Supply ground.

No connect (not bonded); should be connected to VSS.
