FEATURES
■ One half bridge for 7.4A load (ron = 150mΩ)
■ Two half bridges for 5A load (ron = 200mΩ)
■
Two highside drivers for 1.25A load (ron = 800 mΩ)
■ Programmable Softstart function to drive loads
with higher inrush currents (i.e.current >7.4A,
>5A, >1.25A)
PowerSO36
■ Very low current consumption in standby mode
(IS < 3µA, typ. Tj ≤ 85 °C)

DESCRIPTION
The L9951 is a microcontroller driven multifunc-
tional rear door actuator driver for automotive ap-
plications. Up to two DC motors and two grounded
resistive loads can be driven with three half bridg-
es and two highside drivers. The integrated stan-
dard serial peripheral interface (SPI) controls all
operation modes (forward, reverse, brake and
high impedance). All diagnostic informations are
available via SPI.

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