  "textContent": "A large current flowing when energization by normal load drive control is performed at the time of a load short-circuit is prevented. A load drive device includes drive switches and that turn on or off the current supplied from a power source to a load a switch drive circuit that transmits a drive signal to the drive switches and based on a control command from an arithmetic device and a constant current source that supplies the current to the load without passing through the drive switches and Then, the switch drive circuit performs control so as not to turn on either the drive switches or when the voltage between both ends of the load becomes equal to or less than the determination value in a state where the drive switches and are turned off and in a state where the current is supplied from the constant current source to the load",
