1. A control circuit, comprising:
a signal generating circuit configured to generate a pulse width modulation signal; and a drive control circuit configured to alternately turn on a first transistor and a second transistor in accordance with the pulse width modulation signal, the first transistor and the second transistor being connected in series between a wiring to which a first voltage is supplied and a wiring to which a reference potential is supplied, wherein at least one of the first transistor and the second transistor is formed in a P well formed in an N well, and an N-type diffusion layer to be a source or a drain is formed in the P well, the N well is connected to a wiring to which a second voltage lower than the first voltage is supplied via a resistor, and the drive control circuit includes a first drive circuit configured to turn on one of the first transistor and the second transistor when detecting that an electric potential of the N well of the first transistor or the second transistor becomes lower than a first threshold value after the other of the first transistor and the second transistor is turned off. |
