产品概要
描述
The L9951 and L9951XP are microcontroller driven, multifunctional rear door actuator drivers for automotive applications. Up to two DC motors and two grounded resistive loads can be driven with three half bridges and two hide side drivers.
The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedance). All diagnostic information is available via the SPI.

性能一览
- Overload diagnostic for all outputs
- Open load diagnostic for all outputs
- Charge pump output for reverse polarity protection
- Programmable PWM control of all outputs
- Current monitor output for all highside drivers
- All outputs short circuit protected
- One half bridge for 7.4 A load (Ron = 150 m
) - Two highside drivers for 1.25 A load (Ron = 800 m
) - Two half bridges for 5 A load (Ron = 200 m
) - Very low current consumption in stand-by mode (IS < 3μA, typ. Tj ≤ 85°C)
- All outputs over temperature protected
- Programmable softstart function to drive loads with higher inrush currents (i.e.current > 7.4A, >5A, >1.25A)
