Driving apparatus for an inductive load |
摘要 |
A first switching element opens or closes a power supply route of an inductive load in accordance with a first driving signal. A clamping element prevents a voltage ot the power supply route from exceeding a first clamp voltage when the power supply route is opened. A second switching element opens or closes the current flow route, provided in parallel with the power supply route, in response to a second driving signal. A rectifying means is responsive to the second switching element to change the clamp voltage to a second clamp voltage when the first switching element is turned off. The second switching element is constituted by a MOSFET. A charging element charges a capacitor of MOSFET.
