| Title: |
Start-Up Detection in a Dimmer Circuit |
| Abstract: |
Disclosed is an inductive load detection circuit for detecting the
presence of an inductive load on a dimmer circuit. The detection circuit
provides for enhanced detection of the inductive load by detecting
voltage ringing resulting from a turn-off of a switching element in the
circuit. The ringing can be enhanced by providing a faster turn-off rate
in an initial period than a turn-off rate in a steady state period. Also
disclosed is a dimmer circuit comprising the inductive load detection
circuit.
