Abstract:
The embodiments disclosed herein describe a set of fault detection circuits for LED circuits in an LED channel. A first fault detection circuit is configured to detect a short fault across one or more LEDs. A second fault detection circuit is configured to detect an open fault across an LED. A third fault detection circuit is configured to detect a short across an LED channel transistor. A fourth fault detection circuit is configured to detect an LED channel sense resistor open fault. A fifth fault detection circuit is configured to detect if the LED channel is being intentionally unused. These fault detect circuits can be implemented in a fault detection integrated circuit coupled to the LED channel.

Claim (Index 1):
An LED fault detection circuit configured to detect one or more faults of an LED channel comprising one or more LEDs coupled to a drain node of a transistor and a resistor coupled to a source node of the transistor, the circuit comprising:\n a first fault detection circuit coupled to the source node of the transistor and configured to:\n when the LED fault detection circuit is operating in an operating mode, detect an open fault within the one or more LEDs; and \n when the LED fault detection circuit is operating in a calibration mode, detect a short fault across the resistor, wherein the LED fault detection circuit is configured to operate in the calibration mode before being configured to operate in the operating mode; and \n a second fault detection circuit comprising a comparator, a second transistor, and a current source coupled to a drain node of the second transistor, the second fault detected circuit coupled to the source node of the transistor and configured to detect an open fault across the resistor by, when the second transistor is configured to operate as a closed switch, comparing the voltage at the source node of the transistor to a reference voltage and outputting a fault signal indicating a presence or absence of the open fault across the resistor based on the comparison.
