AS8525 Overview
The AS8525 is a panion IC for automotive battery sensor systems for both low-side and high-side current sensing applications. The device provides two regulated 3.3V supplies from the battery supply, attenuated battery voltage in differential form, and amplified version of a high-side current-sense element’s voltage with a translated mon-mode voltage. The device also municates the system output to a LIN bus.
AS8525 Key Features
