Abstract:
A driving apparatus configured to drive a light emitting device includes a driving current source module operable to supply current to the light emitting device via a node during operation. A protection module coupled to the node and the driving current source module selectively injects current to the node during operation. The driving current source module is controlled based on a detection result of a voltage on the node.
Abstract:
An amplifier circuit includes an input terminal and an output terminal. A current sinking transistor includes a first conduction terminal coupled to the output terminal and a second conduction terminal coupled to a reference supply node. A voltage sensing circuit has a first input coupled to the input terminal and a second input coupled to the output terminal. An output of the voltage sensing circuit is coupled to the control terminal of the current sinking transistor. The voltage sensing circuit functions to sense a rise in the voltage at the output terminal which exceeds the voltage at the input terminal, and respond thereto by activating the current sinking transistor.

Abstract:
Described herein is an electronic device. The electronic device includes a unity gain buffer having an input coupled to an input node to receive an input voltage and an output coupled to an output node. A current sink circuit operates in a sleep mode in an absence of a sink current flowing into the output node, and operates in a sinking mode to sink the sink current from the output node to a reference supply node when the sink current flows into the output node.
