PIN DESCRIPTION
Pin No.
Symbol
Description
1
RDLY
Determines the low voltage reset delay and watchdog enable and disable delay.
2
NTEST
Low = test, high = normal operation.
3
INN1
Minus input to channel 1 comparator.
4
INP1
Plus input to channel 1 comparator.
5
INN2
Minus input to channel 2 comparator.
6
INP2
Plus input to channel 2 comparator.
7
INP3
Plus input to channel 3 comparator.
8
INN3
Minus input to channel 3 comparator.
9
INP4
Plus input to channel 4 comparator.
10
INN4
Minus input to channel 4 comparator.
11
THOLD
Variable threshold adjustment.
12
GND
Ground.
13
NOUT4
Inverted output of comparator 4.
14
NOUT3
Inverted output of comparator 3.
15
WDLY
Determines watchdog timing.
16
OLE
Disables outputs. High = normal operation. Low = forces all outputs and comparators high.
17
WD1
Watchdog input.
18
VCC
5.0 V input to IC.
19
WD2
Watchdog input.
20
NLVI
Reset output (in reset when low).
21
LVI
Reset output (in reset when high).
22
WDO
Watchdog output (low for valid watchdog signal).
23
NOUT2
Inverted output of comparator 2.
24
NOUT1
Inverted output of comparator 1.
