Description
The L9950 and L9950XP are microcontroller driven multifunctional door actuator driver for automotive applications.Up to five DC motors and five grounded resistive loads can be driven with six half bridges and five highside drivers. The integrated standard serial peripheral interface (SPI) controls all operation modes (forward, reverse, brake and high impedance). All diagnostic informations are available via SPI.

Highside driver output 11. |
|
|
|
|
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 |
|
2, 35 |
|
OUT11 |
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 |
|
|

This input is low active and requires CMOS logic levels. The serial data |

|
transfer between L9950 and micro controller is enabled by pulling the |

|

to CSN pin the L9950 will be switched into a test mode. |

PWM1 input. |
|

|
PWM1 |
This input signal can be used to control the drivers OUT1-OUT8 and |
|
|
|
|
OUT11 by an external PWM signal. |
|
|
|
|
|
|
|
|
|
Highside driver output 7,8,9,10. |
|
30 |
|
OUT7, |
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 |
||
|
31 |
|
||
|
|
OUT8, |
missing. For ESD reason a diode to GND is present but the energy |
|
|
33 |
|
OUT9, |
which can be dissipated is limited. The highside driver is a power |
|
34 |
|
OUT10 |
DMOS transistor with an internal parasitic reverse diode from the |
|
|

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

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.
