The L9950XP is a microcontroller-driven, multifunctional door actuator driver designed specifically for automotive applications. It can control up to five DC motors and five grounded resistive loads using six half-bridges and five high-side drivers. This versatile IC integrates a standard serial peripheral interface (SPI) to manage all operation modes, including forward, reverse, brake, and high impedance.
Automotive PMIC ic L9950XP Features
The L9950XP offers a comprehensive set of features tailored for automotive door actuators. It includes one full bridge for a 6A load (Ron=150 mΩ), two half-bridges for 3A loads (Ron=300 mΩ), and two half-bridges for 1.5A loads (Ron=800 mΩ). Additionally, it features one high-side driver for a 6A load (Ron=100 mΩ) and four high-side drivers for 1.5A loads (Ron=800 mΩ). The device supports programmable soft-start functions for high inrush currents, low standby current consumption (IS < 6 μA typical), and comprehensive protection features such as short-circuit protection, over-temperature protection, and open-load diagnostics.
L9950XP Applications
The L9950XP is ideal for automotive applications requiring precise control of multiple actuators. It is commonly used in door systems, where it can manage various functions such as window lifts, door locks, and seat adjustments. Its ability to handle multiple loads and provide detailed diagnostics makes it suitable for complex automotive modules that require high reliability and performance.
