A vehicle-mounted driving circuit (10), a vehicle-mounted driving chip (100), a driving device and an electronic device, which relate to the technical field of electronics. The vehicle-mounted driving circuit (10) comprises a driving chip (100), and a first driving transistor (M11) and a first switch transistor (M12), which are used for being connected in series between a power source (20) and a first load (30). The driving chip (100) can turn off the first switch transistor (M12) in response to a first fault signal, and therefore, it can be ensured that a current channel between the power source (20) and the first load (30) is cut off in a timely manner in a fault scenario, thereby preventing damage caused by all elements in the driving circuit (10) and the first load (30) continuing to operate in the fault scenario. The driving chip provides a redundant turn-off path for a first current channel, and therefore, the reliability of the driving circuit (10) during operation is effectively improved.
