MAX25222ATJ/V+T

Power Management - Specialized Overview

The MAX25222ATJ/V+T is a four-channel TFT-LCD power supply and display driver designed for automotive applications. It integrates four high-voltage linear regulators capable of delivering up to 100mA per channel, supporting output voltages from 3V to 24V. The device features an I²C interface for configuration and control, operating within a supply voltage range of 2.65V to 5.5V. It includes built-in protection mechanisms such as thermal shutdown and overcurrent protection. The component operates reliably across an extended temperature range of -40°C to +125°C and is housed in a compact 32-pin TQFN-EP (5x5mm) package with an exposed pad for enhanced thermal performance.
