Overshoot protection circuit for LED lighting

For an LED lighting application, overshoot-protection circuitry prevents an LED controller, such as a matrix lighting controller (MLC) that controls an array of LEDs, from falsely detecting an open-circuit condition in an LED controlled by the LED controller, by limiting the magnitude of an overshoo...

Beschreibung
Zusammenfassung:	For an LED lighting application, overshoot-protection circuitry prevents an LED controller, such as a matrix lighting controller (MLC) that controls an array of LEDs, from falsely detecting an open-circuit condition in an LED controlled by the LED controller, by limiting the magnitude of an overshoot voltage (due to long-wire parasitic inductances) from occurring when a switch in the LED controller that is used to control the LED is turned off.
