APPLICATION INFORMATION
(See Application
Circuit)
The LED driver tells the output status.
It can source or sink current (I
old typ
= 3mA), ac-
cording to the output configurationchosen.
The thresholds, represented by the output com-
parator in the Block Diagram, are set at about
1.5V - 2V.
For instance, in the High Side Load case of the
Application Circuit, when the voltage on pin 8 (the
output) differs from V
CC
lessthan 1.5V, the output
is sensed in ”O(jiān)FF” state and the LED driver is
disabled.
If insteadpin 8 differsfrom V
CC
morethan 3V (the
output comparator threshold value plus the drop
voltage on the LED), then the output is sensed
”O(jiān)N” and the driver will force the current on the
LED.
