CAT3606
Basic Operation
At power-up, the CAT3606 starts operation in 1x mode. If
it is able to drive the programmed LED current, it continues
in 1x mode. If the battery voltage drops to a level where the
LED current cannot be met, the driver automatically
The enable lines ENM and ENS allow to turn On or Off
a group of LEDs as shown in Table 6.

switches into 1.5x mode, to boost the output voltage high

enough to achieve the nominal LED current.
The above sequence is reinitialized each and every time
the chip is powered up or is taken out of shutdown mode (via
EN pin). The use of the Main and Sub display enable pins
(ENM or ENS) does not affect the mode of operation.
LED Current Setting
The LED current is set by the external resistor R SET
connected between the RSET pin and ground. Table 5 lists

The unused LED channels can also be turned off by
connecting the respective LED pins to VOUT. In which
case, the corresponding LED driver is disabled and the
typical LED sink current is only about 0.2 mA. When the
following equation is true on any channel, the driver turns
off the LED channel:
VOUT * V LED v 1 V (LED channel OFF)
Note: The CAT3606 is designed to drive LEDs with forward
voltage greater than 1 V and is not compatible with resistive
loads.
