STMicroelectronics L9908
L9908 is a gate driver unit (GDU) for controlling 6 N-channel FETs for brushless motors in automotive applications. Each one of the 3 half bridge drivers channels (HS/LS couples) can be independently configured allowing different load driving and is able to withstand -14 V to 95 V excursion on motor`s pins. L9908 is equipped with 3 independent high accuracy current monitor channels with SPI-configurable input differential voltage ranges for ground referenced current measurements, with 5 V/3.3 V output dynamic range compatibility.| Part No. | L9908 |
