STMicroelectronics L9953LXP Door Actuator Driver Datasheet
The L9953LXP is a multifunctional door actuator driver designed for automotive applications. It integrates up to three DC motors and three resistive loads, controlled via a standard Serial Peripheral Interface (SPI). The device includes five half bridges and three highside drivers to manage door locks, mirror axis control, and defroster functions.
Key features include programmable soft start for high inrush currents, very low current consumption in standby mode, and comprehensive protection mechanisms such as short circuit, over-temperature, open-load, and overload diagnostics. All diagnostic information is accessible via the SPI interface.
