ABSTRACT:
A sense amplifier adapted to amplify a voltage signal representative of a charging current provided to a rechargeable battery. The sense amplifier may include a p-type input sense amplifier and an n-type input sense amplifier, The p-type input sense amplifier may be enabled and the n-type input sense amplifier may be disabled if a battery voltage level of the rechargeable battery is less than an under voltage threshold level. The p-type input sense amplifier may be disabled and the n-type input sense amplifier may be enabled if the battery voltage level is greater than or equal to the under voltage threshold level. A related method and an electronic device having a sense amplifier consistent with an embodiment are also provided.
