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.

Highside-driver-output 6 |
|
|

|
The output is built by a highside switch and is intended for resistive |

loads, hence the internal reverse diode from GND to the output is |
|
|
|
|
missing. For ESD reason a diode to GND is present but the energy |

|
OUT6 |
which can be dissipated is limited. The highside driver is a power |
|
|
DMOS transistor with an internal parasitic reverse diode from the |

|
|
output to VS (bulk-drain-diode). The output is over-current and open |

Serial data input |
|
8 |
|
DI |
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 |
|

|
CM/PWM2 |
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. |

|
CSN |
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. |

Each output is built by a highside switch and is intended for resistive |
|

|

loads, hence the internal reverse diode from GND to the output is |
|
|
missing. For ESD reason a diode to GND is present but the energy |

|

|
OUT5 |
which can be dissipated is limited. Each highside driver is a power |
|
|
|
|
DMOS transistor with an internal parasitic reverse diode from each |
|
|
|
|
output to VS (bulk-drain-diode). Each output is over-current and open |

load protected. |

2.1Absolute 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
