L9951XPRear door actuator driver
Features One half bridge for 7.4 A load (Ron = 150 mΩ) Two half bridges for 5 A load (Ron = 200 mΩ) Two highside drivers for 1.25 A load on= 800 mΩ) 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 S < 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
Applications Rear door actuator driver with bridges for door
lock and safe lock and two 5W or 10W - light
bulbs.
DescriptionThe 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.
See block diagram. Typical values.

2.1 Absolute maximum ratings
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics sure
program and other relevant quality document
