L9951

` One half bridge for 7.4A load (r<sub>on</sub> = 150m)
` Two half bridges for 5A load (r_on = 200m)
` Two highside drivers for 1.25A load (r<sub>on</sub> = 800 m)
` Programmable Softstart function to drive loads with higher inrush currents (i.e.current >7.4A, >5A, >1.25A)
` Very low current consumption in standby mode(I<sub>S</sub> < 3A, typ. T<sub>j</sub> 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

· Rear Door Actuator Driver with bridges for door  lock and safe lock and two 5W or 10W-light  bulbs.

The L9951 is a microcontroller driven multifunctional rear door actuator driver for automotive applications. Up to two DC motors and two grounded resistive loads can be driven with three half bridges and two 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.
