L9953XP Description
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).
L9953XP Key Features
- 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
- 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
- All outputs over temperature protected
- Open load diagnostic for all outputs
L9953XP Applications
- Door actuator driver with bridges for door lock , mirror axis control, mirror fold and highside driver for mirror defroster and two 10W-light bulbs
