mode. Some newer LEDs include integrated Zener diodes to limit voltage transients, reduce EMI and protect the LEDs, and these must
be driven only in the open-drain mode to prevent overheating the IC.
Change of the outputs at the STOP command allows synchronizing outputs of more than one PCA9633. Applicable to registers from
02h (PWM0) to 08h (LEDOUT) only.

Table 10.
Legend: * default value.
A 97 kHz fixed frequency signal is used for each output. Duty cycle is controlled through
256 linear steps from 00h (0 % duty cycle = LED output off) to FFh
(99.6 % duty cycle = LED output at maximum brightness). Applicable to LED outputs
programmed with LDRx = 10 or 11 (LEDOUT register).
Table 11.
Legend: * default value.
When DMBLNK bit (MODE2 register) is programmed with 0, a 190 Hz fixed frequency
signal is superimposed with the 97 kHz individual brightness control signal. GRPPWM is
then used as a global brightness control allowing the LED outputs to be dimmed with the
same value. The value in GRPFREQ is then a ‘Don’t care’.
General brightness for the 4 outputs is controlled through 256 linear steps from 00h
(0 % duty cycle = LED output off) to FFh (99.6 % duty cycle = maximum brightness).
Applicable to LED outputs programmed with LDRx = 11 (LEDOUT register).
