Product overview
Description
The L9954 and L9954XP are microcontroller driven multifunctional door actuator driver 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). All diagnostic informations are available via SPI.
-
All features
- Overload diagnostic for all outputs
- Open load diagnostic for all outputs
- Charge pump output for reverse polarity protection
- PWM control of all outputs
- Current monitor output for highside OUT1, OUT4, OUT5 and OUT6
- All outputs short circuit protected
- Three half bridges for 1.5A load (Ron=800m
) - Two highside drivers for 1.5A load (Ron=800m
) - One highside driver for 6A load (Ron=100m
) - Very low current consumption in standby mode (IS < 6μA typ; Tj ≤ 85 °C)
- All outputs over temperature protected
- Programmable softstart function to drive loads with higher inrush currents (i.e. current >6A, >1.5A)
