Applications
High Current Applications
Each channel of the ISL97671 can support up to 30mA. For
applications that need higher current, multiple channels can be
grouped to achieve the desirable current. For example, the cathode of
the last LED can be connected to CH0 to CH2, this configuration can be
treated as a single string with 90mA current driving capability.
V OUT
Multiple Drivers Operation
For large LCD panels where more than 6channels of LEDs are
needed, multiple ISL97671s with each driver having its own
supporting components can be controlled together with the
common SMBus/I 2 C. While the ISL97671 does not have extra
pins strappable slave address feature, but a separate EN signal
can be applied to each driver for asynchronous operation. A
trade-off of such scheme is that an exact faulty channel cannot
be identified since both controllers have the same I 2 C slave
address.

16-Bit Dimming
The SMBus/I 2 C controlled PWM and DC dimmings can be
combined to effectively provide 16 bits of dimming capability,
which can be valuable for automotive and avionics display
applications.
