15 GND Ground. Connect the exposed paddle to GND.
8 nINT
Processor Interrupt (Active Low). Requires an external pull-up resistor. If this pin is not used, it can be left
floating. Alternatively, this pin can be set as the PWM input for implementing cABC dimming (see the
PWM Dimming section).
5 nRST
Hardware Reset Input (Active Low). This bit resets the device to the default conditions. If not used, this pin
must be tied above V
IH(MAX)
.
7 SDA I
2
C Serial Data Input. Requires an external pull-up resistor.
6 SCL I
2
C Clock Input. Requires an external pull-up resistor.
