Circuit arrangement for supplying power to e.g. direct current gear motor of motor vehicle, has integrated arithmetic unit adapted to active free-running for integrated half-bridge according to activated condition of activation signal

摘要

The circuit arrangement (100) has two parallel-connected half bridges (111,112,121,122) that comprise two transistors. The half bridges are integrated in an H-bridge circuit module (110,120). An integrated arithmetic unit (113,123) is adapted to active free-running for integrated half-bridge according to activated condition of activation signal. The integrated arithmetic unit is adapted to current through integrated half-bridge. The unit (200) has two supply terminals with center tap terminals (119,119',129,129') electrically connected to half bridges. Independent claims are included for the following: (1) a method for operating circuit arrangement; (2) a processing unit; and (3) a computer program for operating circuit arrangement stored on machine-readable storage medium.
