What this automotive TFT-LCD power IC brings to the board
The MAX25220ATJ/V+ is a 4-channel TFT-LCD power supply IC from Analog Devices, qualified to AEC-Q100 for automotive use. The -40°C to 125°C operating range covers the full under-dash and cabin temperature envelope, including the hot-soak after a summer parking lot exposure. The 1.5 mA supply current is the IC's own draw before the output load; the actual panel power is delivered through external pass elements driven by the four channels.
Package and rework considerations for the 32-TQFN
Housed in a 32-WFQFN with exposed pad, 5x5 mm body (supplier device package 32-TQFN). Without it the junction temperature rises above the 125°C limit under full load. The QFN package is reworkable with hot air if the board has a solder-mask-defined pad and the adjacent components clear the nozzle footprint.
