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 < 3A, 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.
