General Description
The MAX16826 high-brightness LED (HB LED) driver is designed for backlighting
automotive LCD displays and other display applications such as industrial or
desktop monitors and LCD televisions. The MAX16826 integrates a switching
regulator controller, a 4-channel linear current sink driver, an analog-to-
digital converter (ADC), and an I2C interface. The IC is designed to withstand
automotive load dump transients up to 40V and can operate under cold crank
conditions.
The MAX16826 contains a current-mode PWM switching regulator controller that
regulates the output voltage to the LED array. The switching regulator section
is configurable as a boost or SEPIC converter and its switching frequency is
programmable from 100kHz to 1MHz.
The MAX16826 includes 4 channels of programmable, fault-protected, constant-
current sink driver controllers that are able to drive all white, RGB, or RGB
plus amber LED configurations. LED dimming control for each channel is
implemented by direct PWM signals for each of the four linear current sinks.
An internal ADC measures the drain voltage of the external driver transistors
and the output of the switching regulator. These measurements are then made
available through the I2C interface to an external microcontroller (μC) to
enable output voltage optimization and fault monitoring of the LEDs.
The amplitude of the LED current in each linear current sink channel and the
switch-mode regulator output voltage is programmed using the I2C interface.
Additional features include: cycle-by-cycle current limit, shorted LED string
protection, and overtemperature protection. The MAX16826 is available in a
thermally enhanced, 5mm x 5mm, 32-pin thin QFN package and is specified over
the automotive -40°C to +125°C temperature range.
