Abstract: A battery charger includes a relay having a first terminal and a second terminal. A capacitor has a first terminal and a second terminal. The first terminal is coupled to the second terminal of the relay. A clamp circuit is coupled to the second terminal of the capacitor. A reference voltage circuit has an output terminal. A comparator has a first comparator input terminal coupled to the second terminal of the capacitor and has a second comparator input terminal coupled to the output terminal of the reference voltage circuit.
