A vehicle-mounted drive circuit (10), a vehicle-mounted drive chip (100), a drive part, and an electronic device are provided, and relate to the field of electronic technologies. The vehicle-mounted drive circuit (10) includes the drive chip (100), and a first drive transistor (M11) and a first switching transistor (M12) connected in series between a power supply (20) and a first load (30). Because the drive chip (100) can cut off the first switching transistor (M12) in response to a first fault signal, it may be ensured that a current channel between the power supply (20) and the first load (30) is cut off in a timely manner in a fault scenario, to avoid a case in which each element in the drive circuit (10) and the first load (30) are damaged when continuously operating in the fault scenario. Because the drive chip provides a redundant shut off path for a first current channel, reliability of the drive circuit (10) during operation is effectively improved.
