Symbol Input/output Description
RST1 Output First reset output, active-high, push-pull.
R
ST2 Output Second reset output, active-low, open-drain.
S
R0 Input Primary push-button Smart Reset input. Active-low.
S
R1 Input Secondary push-button Smart Reset input. Active-low.
TSR Input
A Three-state Smart Reset input delay setup control. When connected
to ground, t
SRC
= 2 s; when left open, t
SRC
= 6 s; when connected to
V
CC
, t
SRC
= 10 s (all times are minimum). TSR is a DC-type input,
intended to be either permanently grounded, permanently connected
to V
CC
or permanently left open. If left open, for improved system glitch
immunity it is strongly recommended to connect a 0.1 µF decoupling
ceramic capacitor between the TSR and V
SS
pins.
TREC
ADJ
Input
Input pin for t
REC1
reset pulse duration adjustment. Connect an
external capacitor C
tREC
to this pin to determine t
REC1
; t
REC2
is factory-
programmed.
V
CC
Supply
Positive supply voltage input. Power supply for the device and an input
for the monitored supply voltage. A 0.1 µF decoupling ceramic
capacitor is recommended to be connected between V
CC
and V
SS
pins.
