16-Channel Automotive Local-Dimming Backlight Driver with SPI Interface

General Description

Beneﬁts and Features

● High Integration

The MAX21610 is a 16-channel modular backlight driver for

use with automotive displays. The integrated current outputs

can sink up to 100mA LED current, each depending on the

ambient temperature. Device power comes from an external

3.3V or 5V supply, while the LED current-sink outputs can

operate at up to 17V.

• Complete 16-Channel Solution with Independent

Dimming and Daisy-Chain Option

• SPI Control for Minimum Parts Count

● Robust and Low EMI

• Programmable Spread Spectrum On Outputs

• Slew-Rate Controlled Switching On LED Outputs

• Programmable Phase Shift Between Outputs

A feedback output pin (FB) is provided to control an external

DC-DC converter so that voltage headroom can be optimized

and the overall system power dissipation reduced.

● Relative Dimming Ratio Between Strings Up to32768:1

● Latch Input (RST_LAT) for Synchronization to Video

Frame

● FB Output to Control External Power Supply for

Minimum System Power Dissipation

● 1% Accurate Output Current

The global LED current for all strings is set through a serial

peripheral interface (SPI), with individual PWM settings for

each of the channels. The PWM frequency can be determined

using the internal oscillator or by synchronizing to the external

CLKIO input.

● Complete Diagnostics

The device features a high-speed SPI interface for control.

Up to 10 devices can be daisy-chained to reduce connection

complexity.

• LED Open/Short Detection and Protection

• Power Supply Overvoltage Protection

• Thermal Warning

The MAX21610 is available in a TQFN package and operates

in the -40 to 125°C temperature range.

• Thermal Shutdown

● Compact 32-Pin TQFN 5mm x 5mm Package

Applications

● Infotainment Displays

● Central Information Displays

● Instrument Clusters
