    摘要: A programmable fuse state determination system and method provide a fuse current through a programmed fuse which produces a voltage that varies with the fuse's resistance. The voltage is compared with a threshold voltage to indicate whether the fuse is blown or intact. The invention employs ‘normal’ and ‘test’ modes, in which the relationship between the fuse's resistance and the threshold voltage differ, such that a higher fuse resistance is required for the fuse to be determined blown in the ‘test’ mode than in the ‘normal’ mode.

    摘要: A dynamically read fuse cell includes a first circuit which includes a known reference resistance Rref, and a second circuit which includes a programmed fuse having a resistance Rfuse; the state of the programmed fuse is to be read. The first and second circuits receive a common “read” signal, and are arranged to produce first and second outputs which begin changing state in response; the first and second outputs have respective slew rates which vary with Rref and Rfuse, respectively. The first and second circuits are interconnected such that causing both outputs to begin changing state in response to the “read” signal triggers a time domain race condition, the result of which indicates which of the outputs slewed more quickly in response to the “read” signal, thereby indicating the relationship between Rref and Rfuse and, when Rref is properly chosen, the state of the fuse.

    摘要: A communication system includes a master device which communicates with a chain of serially-connected slave devices. The master originates messages, each of which is intended for a particular ‘target’ slave device. Each message contains a ‘distance to target device’ value equal to the number of devices between the master and target, and a data packet containing data to be conveyed between the master and target. Each slave device determines if the ‘distance to target device’ value indicates that it is the target. If not, the slave device increments or decrements the value in real time, with no latency, and transmits the modified message to the next slave device until received by the target device. In one embodiment, the target device may place data in the data packet, and the slave devices are arranged to buffer the data back to the master device.

    摘要: An anti-cross conduction driver control circuit and method prevent the occurrence of race conditions and avoid cross-conduction between series-connected power devices, typically MOSFETs, controlled in accordance with the present invention. Individual state machines are connected across the inputs and outputs of each power device driver, and are arranged to accurately determine when the driver has completed a task requested of it. Each state machine produces a “lockout” signal based on driver status, which is used to inhibit the operation of the opposite driver under prescribed conditions, and to thereby prevent cross-conduction between the series-connected power devices.

    摘要: A programmable “semi-fusible” link system is used to trim one or more circuit parameters. Each semi-fusible link, typically a thin film resistor, has “intact” and “blown” states, with the link having a first, non-zero resistance when intact, and a second, higher but finite resistance when blown, which is accomplished by forcing a predetermined current through the link. Each link is connected to a respective active devices which, when turned on, provide the current needed to blow the link. The links are also connected in series with respective current sources, and to respective threshold detectors connected to monitor the current through their respective links. Each threshold detector provides a logic output which indicates whether its link is intact or blown based on the magnitude of the link current. A “disable” circuit may also be included which, when activated, prevents the further programming of any of the circuit's semi-fusible links.
