A battery charging apparatus includes a first switch, a second switch, a third switch and a fourth switch connected in series between an input voltage bus and ground, wherein a common node of the second switch and the third switch is configured to be coupled to a battery, a flying capacitor connected between a common node of the first switch and the second switch, and a common node of the third switch and the fourth switch, and a controller configured to generate gate drive signals for configuring at least one switch of the first switch and the second switch as a linear regulator during a charging process of the battery.

Battery charging apparatus and method thereof

A battery charging apparatus includes a first converter having an input coupled to an input voltage bus and an output coupled to a first battery, and a second converter having an input coupled to the input voltage bus and an output coupled to the first battery and a second battery through a first bidirectional current blocking switch and a second bidirectional current blocking switch, respectively.

Dual-battery charging apparatus and control method

In accordance with an embodiment, an integrated circuit comprises a master-slave flip-flop, a selection logic circuit, and a pass structure. The selection logic circuit is configured to selectively enable or disable one or more clock signals. The pass structure is configured to pass a data signal to the master-slave flip-flop in response to a selected clock signal being enabled.
