Abstract

See full text

This disclosure is directed to a light emitting diode (LED) circuit for driving two or more different LED strings, which may be controlled in a complimentary fashion. The LED circuit includes current monitoring capabilities that are configured to monitor current through the two or more different LED strings. The circuit is designed in a way that can reduce or eliminate excessive sensing pins that are otherwise needed for the current monitoring. According to this disclosure, for example, very accurate current monitoring can be achieved by using two or more sensing resistors while only using two sensing pins for the current monitoring through two or more different LED strings.
