摘要： An electronic circuit combines a synchronous switching regulator circuit with an overvoltage detection circuit. The overvoltage detection circuit is configured to generate an overvoltage signal capable of an overvoltage state indicative of a power supply voltage being above a predetermined threshold voltage. The switching regulator circuit is coupled to receive the overvoltage signal. The switching regulator is also configured, in response to the overvoltage signal being in the overvoltage state, to generate a first control signal resulting in at least one of two series coupled transistors being in an off condition.

摘要： Apparatus and methods for detecting passing magnetic articles using a first, True Power On State (TPOS) detector during a first time interval and transitioning to a second, running mode detector after the first time interval, when the output of the second detector is accurate. A phase comparator is responsive to the output signal of the first and second detectors and provides a control signal indicative of a change in the phase relationship between the two output signals. An output switch controlled by the phase comparator provides, as the detector output signal, the first detector output signal during the first time interval and the second detector output signal thereafter. A threshold signal associated with the TPOS detector is at a fixed level during a first portion of the first time interval and is adjusted during a second portion of the first time interval in response to an automatic gain control circuit in order to reduce the phase error associated with transitioning from the TPOS detector to the running mode detector. Also described are apparatus and methods for updating a running mode threshold signal that is a percentage of the peak-to-peak magnetic field sensor signal, so that unnecessary update events are reduced.

摘要： An integrated circuit includes a monitor node adapted to receive a monitored signal. The integrated circuit also includes a multi-purpose node. The integrated circuit is adapted to receive and store a threshold presented at the multi-purpose node during a first time period. The integrated circuit is also adapted to output a fault signal from the multi-purpose node at a time after the predetermined time period. The fault signal is indicative of a relationship between the monitored signal and the threshold. With this arrangement, the multi-purpose node achieves at least two functions.
