Description

General part information

MAX20446 Series

The MAX20446 is a 6-channel backlight driver with boost controller for automotive displays. The integrated current outputs can sink up to 130mA LED current each. The device accepts a wide 4.5V to 36V input voltage range and withstands direct automotive load-dump events.The internal current-mode switching DC-DC controller supports boost or SEPIC topologies and operates in the frequency range 400kHz to 2.2MHz. Integrated spread spectrum helps reduce EMI. An adaptive output-voltage control scheme minimizes power dissipation in the LED current-sink paths.The device features I2C-controlled pulse-width modulation (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 also available via the I2C interface.The MAX20446 is available in a TQFN package and operates in the -40°C to 125°C temperature range.Design Solution: Overcome the Design Challenges of New Automotive Display Backlights ›ApplicationsCentral Information DisplaysInfotainment DisplaysInstrument Clusters
