SNVS857 – FEBRUARY 2014
9.2.4 Application With 12 LED Strings, I2C Brightness Control
In the following example full 12 channels are used with I2C brightness control. PWM/INT terminal is used for
interrupt signal, notifying processor on possible fault conditions. LED current and PWM frequency are set with
I2C writes, or default EPROM values can be used as well. Component selection and performance plots follow the
examples shown in first application example with default EPROM configuration. Configuration registers can be
set before backlight is enabled, so special pre-set EPROM is not necessarily needed. Details on I2C registers
and EPROM settings are seen in the Register Map section. If custom EPROM is required, please contact TI
Sales representative for availability.
