CAN receiver wake-up circuit |
摘要 |
A wake-up circuit for a ECU on a CAN bus utilizes two complementary switching transistors which will turn ON when there is a differential voltage between CANH and CANL which will turn ON the transistors to pass a current which will be mirrored over to create a voltage which will switch a comparator or a Schmitt trigger. The two signals are then ORed together to generate a digital wake-up signal that can be utilized by other on-chip circuitry.
