L9952XPTR

Power Management - Specialized Overview

The L9952XPTR is a multifunctional door actuator driver designed for automotive applications, manufactured by STMicroelectronics. It integrates six half bridges and five high-side drivers to control up to five DC motors and five grounded resistive loads. The device features an integrated standard Serial Peripheral Interface (SPI) for operation mode control and diagnostic feedback. Key electrical characteristics include a full bridge rated for 6A load with 150 mΩ on-resistance, two half bridges for 3A loads at 300 mΩ, and two for 1.5A loads at 800 mΩ. High-side drivers support 6A at 100 mΩ and four channels for 1.5A at 800 mΩ. Standby current consumption is typically below 6 μA.
