L9951 Rear Door Actuator Driver
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.
技术特性
- One half bridge for 7.4 A load (Ron = 150 m Ω )
- Two half bridges for 5 A load (Ron = 200 m Ω )
- Two highside drivers for 1.25 A load (Ron = 800 m Ω )
- Programmable softstart function to drive loads with higher inrush currents (i.e.current > 7.4A, >5A, >1.25A)
- Very low current consumption in stand-by mode (IS < 3μA, typ. Tj ≤ 85°C)
- All outputs short circuit protected
- Current monitor output for all highside drivers
- All outputs over temperature protected
- Open load diagnostic for all outputs
- Overload diagnostic for all outputs
- Programmable PWM control of all outputs
- Charge pump output for reverse polarity protection
