Title: Control circuit
Inventor: UENO AKIHISA
IPC: H03K17/08
Filed: 2012-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a control circuit 1 that is improved in reliability.SOLUTION: The control circuit includes a capacitor 50, and a comparator 64 fed with a supply voltage from the capacitor 50. When an output voltage of a common connection terminal 25 becomes lower than a reference voltage output from a common connection terminal 65c, the comparator 64 determines that the potential of the common connection terminal 25 is a negative potential, and the level of an output signal of the comparator 64 changes from a low level to a high level. This turns on an nMOS transistor 61. A current then flows from a ground side to a negative power supply Vm via the nMOS transistor 61, diodes 62, D1, the common connection terminal 25 and a switch SW. This protects a drive circuit of the control circuit 1 against damage. It is thus possible to prevent a negative voltage surge from damaging the drive circuit 30 and the like.
