Abstract
A sensor having a power management mechanism controlled by an external trigger signal is presented. The sensor includes a magnetic field signal generating circuit and a control circuit coupled to the magnetic field signal generating circuit. The control circuit, responsive to an externally generated trigger signal, initiates a supply current pulse that activates the magnetic field signal generating circuit for a predetermined time interval.
