H-bridge apparatus and method

摘要

An apparatus has a first H-bridge having a first motor contact on a shared first side and a second motor contact on a second side. The apparatus also has a half H-bridge having a third motor contact on a third side, wherein the shared first side of the first H-bridge and the third side of the half H-bridge may be operated as a second H-bridge. Another apparatus has a first H-bridge having a first motor contact on a shared first side and a second motor contact on a second side. The other apparatus also has a switch coupled to a third motor contact, wherein the shared first side of the first H-bridge and the switch may be operated as a partial H-bridge. A method of operating an alternate H-bridge and a method of flexibly using an H-bridge circuit on an ASIC are also provided.
