ABSTRACT:
An integrated circuit battery sensor and system thereof are provided. The battery sensor includes a voltage sensor configured to sample a voyage of a battery and a buffer in electrical communication with the voltage sensor and configured for scaling the sampled battery voltage and outputting a voltage signal proportional to the sampled battery voltage; wherein the voltage sensor is further configured for isolating the buffer from the battery. The voltage sensor includes a first capacitor coupled to a positive potential terminal of the battery and a second capacitor coupled to a negative potential terminal of the battery. The battery sensor includes a first die including a first and second input terminal configured for coupling to the positive and negative potential terminals of the battery; and a second die including the voltage sensor, wherein the first and second die are electrically isolated from each other.
