MAX25024

Automotive Low Input Voltage I C 4-Channel

150mA Backlight Driver supporting ASIL B

General Description

Benefits and Features

The MAX25024 is a 4-channel backlight driver IC with

boost controller for automotive displays. The integrated

current outputs can sink up to 150mA LED current each.

The device accepts a wide 2.5V to 36V input voltage

range and withstands automotive load-dump events.

● Wide Voltage-Range Operation

• Operates Down to 2.5V Supply After Startup

• Survives Load Dumps Up to 40V

● High Integration

• Complete 4-Channel Solution Including Boost

Controller

The internal current-mode switching DC-DC controller

supports boost or SEPIC topologies and operates in the

400kHz to 2.2MHz frequency range. Integrated spread

spectrum helps reduce EMI. An adaptive output-voltage-

control scheme minimizes power dissipation in the LED

current-sink paths.

• I C Control for Minimum Parts Count

● Robust and Low EMI

• Spread-Spectrum Oscillator

• Phase Shifting

• 400kHz to 2.2MHz Switching-Frequency Range

• nMOS Input Protection Switch

Control is included for an external nMOSFET series switch

to reduce quiescent current when the backlight is off and

to disconnect the boost converter in the case of a fault.

● Multiple Features for ASIL B Systems

• LED-Current Measurement

The device features I C-controlled pulse-width-modu-

• Boost Input Current Measurement

• Boost Output Voltage Measurement

• LED Open/Short Detection and Protection

• Boost Output Undervoltage and Overvoltage

lation (PWM) dimming and hybrid dimming. In either case,

the minimum pulse width is 500ns. Phase-shifted dimming

of the strings is incorporated for lower EMI.

Comprehensive diagnostic information is available

through the I C interface to ease integration in systems re-

● Versatile Dimming Scheme Allows Hybrid or PWM-

Only Dimming Using DIM Input or I C

quiring ASIL B compliance.

• Dimming Ratio > 10,000:1 Using Hybrid Dimming

• 10,000:1 Dimming Ratio at 200Hz Using PWM

Dimming

The MAX25024 is available in a 24-pin TQFN or 24-pin

side-wettable TQFN (SWTQFN) package and operates

over the -40°C to +125°C temperature range.

● Compact (4mm x 4mm) 24-Pin TQFN and SWTQFN

Packages

Applications

● Instrument Clusters

Ordering Information appears at end of data sheet.

● Central Information Displays

● Infotainment Displays
