Description
The L9954 and L9954XP are microcontroller driven, multifunctional door actuator drivers for automotive applications. Up to two DC motors and three grounded resistive loads can be driven with three half bridges and three highside 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.

The output is built by a highside and a lowside switch, which are internally connected. The output stage of both switches is a power DMOS transistor. Each driver has an internal parasitic reverse diode (bulk-drain-diode: highside driver from output to VS, lowside driver from GND to output). This output is over-current and open load protected.
Power supply voltage (external reverse protection required) For this input a ceramic capacitor as close as possible to GND is
recommended.
S
Important: for the capability of driving the full current at the outputs all pins of VS must be externally connected.
Serial data input The input requires CMOS logic levels and receives serial data from the
microcontroller. The data is an 24bit control word and the least significant bit (LSB, bit 0) is transferred first.
Current monitor output/PWM2 input Depending on the selected multiplexer bits of Input Data Register this
output sources an image of the instant current through the corresponding highside driver with a ratio of 1/10.000. This pin is bidirectional. The microcontroller can overdrive the current monitor signal to provide a second PWM input for the output OUT5.
Chip select not input / testmode This input is low active and requires CMOS logic levels. The serial data
transfer between L9954 and micro controller is enabled by pulling the input CSN to low level.
Serial data output The diagnosis data is available via the SPI and this tristate-output. The
output will remain in tristate, if the chip is not selected by the input CSN (CSN = high)
