Maxim Integrated (MAX20444CATG/VY+) Display Driver, I2C, 4.5 V to 36 V

Product Information No. of Digits: - No. of Segments: - Driver Case Style: SWTQFN-EP No. of Pins: 24Pins Supply Voltage Min: 4.5V Supply Voltage Max: 36V Interface Type: I2C Operating Temperature Min: -40°C Operating Temperature Max: 125°C Product Range: - MSL: MSL 1 - Unlimited General Description The MAX20444C is a 4-channel backlight driver IC 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 400kHz to 2.2MHz frequency range. Integrated spread spectrum helps reduce EMI. An adaptive output voltagecontrol 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 through the I2C interface, while stand-alone operation is also supported. The MAX20444C 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.
