L9954 Datasheet Door ACtuator Driver

Manufacturer: STMicroelectronics

Overview: L9954 L9954XP Door actuator driver.

Datasheet Details

The L9954 and L9954XP are microcontroller driven, multifunctional door actuator drivers for automotive applications.

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

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

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 standby mode (IS < 6µA typ; Tj ≤ 85 °C).
All outputs short circuit protected.
Current monitor output for highside OUT1, OUT4, OUT5 and OUT6.
All outputs over temperature protected.
