CPO (Pin 1): Output of the Charge Pump. Used to power
all LEDs. A 4.7μF X5R or X7R ceramic capacitor should
be connected to ground.
ULED1-ULED12 (Pins 2-6,12-18): Current Source Outputs
for Driving LEDs. The LED current can be set from 0mA
to 27.5mA in 64 steps via software control and internal
6-bit linear DAC. Each output can be disabled by setting
the associated data register REG1 to REG12 low. ULED1
to ULED12 can also be used as I 2 C controlled open-drain
general purpose outputs. Connect unused outputs to
ground.
CAM (Pin 7): Current Source Output for the CAM Display
White LED. The LED on the CAM display can be set from
0mA to 425mA in 16 steps via software control and in-
ternal 4-bit linear DAC. Two 4-bit registers are available.
One is used to program the high camera current and the
second the low camera current. These registers can be
selected via the serial port or the CAMHL pin. The output
can be disabled by setting data in REG13 low. A safety
timer will disable the output after two seconds whenever
the high camera current mode is selected (see Applica-
tions Information).
