Patent number: 10439510Abstract: In an example embodiment, an apparatus includes a bridge rectifier circuit having branches between the AC and DC nodes formed by a set of transistors. A load current measurement circuit includes a current-controlled current source coupled to the bridge rectifier circuit. The current control current source is configured to generate a mirrored current that is a scaled version of a current through at least one of the set of transistors. A current integration circuit is configured to integrate the mirrored current by charging a capacitor with the scaled current in a first mode and discharging the capacitor in a second mode. A sample and hold circuit is configured to set an output node to a voltage equal to a voltage stored by the capacitor in response to the current integration circuit entering the second mode and prior to the discharge of the capacitor.Type: GrantFiled: March 14, 2017Date of Patent: October 8, 2019Assignee: NXP B.V.Inventors: Peter Christiaans, Robert Glenn Crosby, II, Fu Chun Zhan
