  • Publication number: 20240314909
    Abstract: A LED driver chip includes driver circuits, each being coupled to a different pin and including a fault-detection circuit. Each fault-detection circuit includes a force circuit forcing current to a force node, and a sense circuit including a current sensor coupled to the force node, and a comparator comparing a voltage at the force node to a reference voltage to generate a comparison output. Control circuitry, in a pin-to-pin short detection mode, activates the force circuit of a first of the driver circuits and activates thep sense circuit of a second of the driver circuits, in a pin-to-ground short detection mode, activates the force and the sense circuit of the same driver circuits. The comparison output of the comparator of the activated sense circuit, if is higher or if lower of the reference voltage, indicates if short between pin or to ground, respectively, is present.

  • Patent number: 12093193
    Abstract: Individual bits of a K bit unary data word, wherein K is greater than one, are applied to K polyphase finite impulse response filter circuits. Each polyphase finite impulse response filter circuit receives a different bit and operates with a single bit precision to generate from each received bit a filtered output data word. A gain adjustment is applied by a gain stage circuit to each filtered output data word to generate a corresponding gain adjusted output data word. The gain adjusted output data words from the gain stage circuits are summed to generate an output data word. The unary data word may be output from a source such as a data encoder or a quantizer.
