Pin definitions and functions

Symbol

Function

Supply voltage; Connected to battery or supply control switch, with EMC

filter

8GND

Ground; Signal ground

4IN_SET

Control input for OUT channel; Connect to a low power resistor to adjust

OUT output current. Alternatively, a different current reference (i.e. the

OUT_SET of another LITIX™ Basic+ LED Driver) may be connected

2OUT_SET

Control output for additional current source; If an additional channel or

output current with same input control is needed, connect this pin to the

IN_SET pin of the additional LED driver. If not used, leave the pin open

6PWMI

PWM input; Connect to an external PWM controller. If not used, connect to

GND

1SLS_REF

Single LED short reference input; Connect to a low power resistor or a

voltage reference to adjust Internal SLS threshold. If not used, connect to

GND

5DS

Single LED short delay/restart input; Connect to a capacitor, leave open or

connect to GND, depending on the required diagnosis management for single

LED short detection (see Chapter 6 for further details)

Disable/delay error input; Connect to a capacitor, leave open or connect to

GND, depending on the required diagnosis management (see Chapter 6 for

further details)

ERRN

ERROR flag I/O; Open drain, active low. Connect to a pull-up resistor
