EMX5501AA – High Efficiency Automotive Power Management IC for Car Navigation LCD Display Panels

Optimized for Automotive Display Power
The EMX5501AA is a highly integrated Power Management IC (PMIC) specifically designed for modern automotive infotainment systems. It provides a complete power supply solution for TFT-LCD display panels used in car navigation, center stacks, and digital instrument clusters.

High-Efficiency Power Architecture
This IC integrates a synchronous boost converter and a gate driver for panel operation. It is engineered to deliver stable voltage regulation even under the noisy conditions of vehicle electrical systems.

Advanced Protection Features
The device includes critical protective circuitry such as Over-Voltage Protection (OVP), Under-Voltage Lockout (UVLO), Over-Current Protection (OCP), and Thermal Shutdown. These features ensure fail-safe operation within the harsh automotive cabin environment (temperature rating up to +105°C).

Wide Compatibility for Infotainment
Designed for the aftermarket and OEM replacement markets, the EMX5501AA supports high switching frequencies (up to 2.1MHz). This allows designers to use smaller external components while maintaining excellent EMI performance.

Reliable and Stable Supply
It offers precise regulation for AVDD, VGH, VGL, and VCOM voltages, ensuring high-quality image stability on LCD screens without flickering or line noise.
