MAX16826

Programmable, Four-String HB LED Driver with

Output-Voltage Optimization and Fault Detection

General Description

Features

♦ External MOSFETs Allow Wide-Range LED

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 cur-

rent sink driver, an analog-to-digital converter (ADC),

Current with Multiple LEDs per String

♦ Individual PWM Dimming Inputs per String

♦ Very Wide Dimming Range

♦ LED String Short and Open Protection

♦ Adjustable LED Current Rise/Fall Times Improve

and an I C interface. The IC is designed to withstand

automotive load dump transients up to 40V and can

operate under cold crank conditions.

EMI Control

♦ Microcontroller Interface Using I C Allows

LED Voltage Monitoring and Optimization

Using a 7-Bit Internal ADC

LED Short and Open Detection

Dynamic Adjustment of LED String Currents

and Output Voltage

The MAX16826 contains a current-mode PWM switching

regulator controller that regulates the output voltage to

the LED array. The switching regulator section is config-

urable as a boost or SEPIC converter and its switching

frequency is programmable from 100kHz to 1MHz.

Standby Mode

♦ Integrated Boost/SEPIC Controller

♦ External Switching Frequency Synchronization

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 chan-

nel 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.

♦ 4.75V to 24V Operating Voltage Range and

Withstands 40V Load Dump

♦ Overvoltage and Overtemperature Protection

/V denotes an automotive qualified part.

The amplitude of the LED current in each linear current-

sink channel and the switch-mode regulator output volt-

age is programmed using the I C 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.
