Rear 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

(Ron =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

(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

Applications

■ Rear door actuator driver with bridges for door

lock and safe lock and two 5W or 10W - light

bulbs.

Description

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.
