摘要： A circuit comprises a battery field-effect transistor (FET) coupled between a battery and an electronic system so that current from the battery flows through the battery FET to the electronic system. A replica FET couples the battery to a current sensing circuit. One of the battery FET and the replica FET comprises a plurality of parallel FET segments having separate control terminals. A logic block provides a plurality of switch control signals based on a system state input. A switching circuit receives the switch control signals and selectively couples the separate control terminals of the FET segments to one of a first reference voltage terminal or a second reference voltage terminal to independently turn each FET segment on or off. The current sensing circuit provides a voltage indicative of the current flowing through the replica FET.

摘要： A voltage detecting system is configured for detecting a voltage supplied to an electronic device. The voltage detecting system includes a voltage measuring circuit configured to measure the voltage, a voltage converting circuit electrically coupled to the voltage, and a voltage comparing circuit. The voltage measuring circuit has a first measuring range and a second measuring range that is wider than the first measuring range. The voltage converting circuit is capable of the converting the voltage to an output voltage according to a predetermined ratio. The voltage comparing circuit compares the output voltage with a reference voltage. If the output voltage is greater than the reference voltage, the voltage comparing circuit informs the voltage measuring circuit to select the second measuring range. If the output voltage is not greater than the reference voltage, the voltage comparing circuit informs the voltage measuring circuit to select the first measuring range.

摘要： A method for obtaining field strength information from a received electromagnetic signal by a receiver unit is provided, whereby an input voltage for an operational amplifier is generated from the received signal in the receiver unit by means of an input resistance realized as a voltage divider circuit and an output voltage is generated by the operational amplifier by means of a fixed amplification factor. The input voltage is changed until the output voltage lies within a predefined interval that includes the value of the reference voltage. The input voltage is tapped at the voltage divider circuit and, to change the input voltage at the voltage divider circuit, which has a plurality of divider nodes and a constant resistance value, a divider node is selected and a partial voltage is tapped. The field strength value received by the receiver unit is determined from a comparison of a quantity assigned to the selected divider node.
