L9954XP Overview
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).
L9954XP Key Features
- 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
- 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
- Open load diagnostic for all outputs
- Overload diagnostic for all outputs
L9954XP Applications
- Door actuator driver with bridges for mirror axis control and highside driver for mirror defroster and two 10W-light bulbs
