L9953XP Datasheet Door ACtuator Driver

Manufacturer: STMicroelectronics

Overview: L9953 L9953XP Door actuator driver.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

The L9953 and L9953XP are microcontroller driven multifunctional door actuator driver for automotive applications.

Up to three DC motors and three grounded resistive loads can be driven with five half bridges and three highside drivers.

The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedance).

One full bridge for 6A load (Ron=150mΩ).
Three half bridges for 1.5A load (Ron=800mΩ).
One highside driver for 6A load (Ron=100mΩ).
Two highside drivers for 1.5A load (Ron=800mΩ).
Programmable softstart function to drive loads with higher inrush currents (i. e. current >6A, >1.5A).
Very low current consumption in stand-by mode (IS < 6µA typ; Tj ≤ 85 °C).
All outputs short circuit protected.
Current monitor output for highside OUT1, OUT4, OUT5 and OUT8.
