Abstract
A driving device includes, for example: an output terminal; a transistor configured to generate an output current to the output terminal; a logic circuit configured to perform on/off control of the transistor at a predetermined period; and a current sense circuit configured to sense the output current. The current sense circuit is configured to be enabled during an on-period of the transistor. The logic circuit is configured to suspend the on/off control and reset the period when the output current becomes lower than a first threshold value during the on-period.
Claims10
A driving device comprising:
- an output terminal;
- a transistor configured to generate an output current to the output terminal;
- a logic circuit configured to perform on/off control of the transistor at a predetermined period;
- and
- a current sense circuit configured to sense the output current,
- wherein
- the current sense circuit is configured to be enabled during an on-period of the transistor, and
- the logic circuit is configured to suspend the on/off control and reset the period, when the current sense circuit detects that the output current becomes lower than a first threshold value during the on-period.
