CAT3616
Application Information
Single Wire Dimming Application
The dimming control can be achieved through a single
wire interface by connecting together all three logic input
signals EN, ENM and ENS as shown on Figure 25.
The common enable signal is set high to enable the driver.
On the first negative going pulse, the LEDs turn full on. The
pulse low state duration (between the falling and rising
edges) must be shorter than 0.5 msec. Any consecutives
pulses reduce the LED current by 1 mA. The enable signal
is kept low for more than 1.5 msec to turn off all the LED
channels and set the driver in shutdown mode, as shown on
Figure 26.
