Product overview
描述
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). All diagnostic informations are available via SPI.
-
All features
- Open load diagnostic for all outputs
- All outputs over temperature protected
- Separated half bridges for door lock motor
- Overload diagnostic for all outputs
- Charge pump output for reverse polarity protection
- PWM control of all outputs
- All outputs short circuit protected
- Very low current consumption in stand-by mode (IS < 6μA typ; Tj ≤ 85 °C)
- One full bridge for 6A load (Ron=150m
) - One highside driver for 6A load (Ron=100m
) - Three half bridges for 1.5A load (Ron=800m
) - Programmable softstart function to drive loads with higher inrush currents (i.e. current >6A, >1.5A)
- Current monitor output for highside OUT1, OUT4, OUT5 and OUT8
- Two highside drivers for 1.5A load (Ron=800m
)
