MAX25024ATG/V+T

Price range: $3.55

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.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.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.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 available through the I2C interface to ease integration in systems requiring ASIL B compliance.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.ApplicationsCentral Information DisplaysInfotainment DisplaysInstrument Clusters
