Abstract: A charge pump circuit includes a voltage output terminal, a flying capacitor, and a current source. The flying capacitor includes a first terminal coupled to the voltage output terminal, and a second terminal coupled to an output terminal of a drive circuit. The current source includes a first terminal coupled to the voltage output terminal, and a second terminal coupled to a power supply rail.

Abstract: An method comprising activating an internal switch within a packaged electronic device to connect to a reference ground of an internal voltage source to a first input of an analog front end, receiving an external ground potential voltage at a first package pin of the packaged electronic device, generating a zero detector output signal for the packaged electronic device at a second package pin, activating the internal switch to connect the first input of the analog front end to the internal voltage source, receiving a second voltage level at the first package pin that generates a second output signal that matches the zero detector output signal, and receiving trim instructions to trim an internal voltage generated by the internal voltage source to a voltage level that is closer to a target voltage level.
