ams AS8525
The AS8525 is a companion 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 common-mode voltage. The device also communicates the system output to a LIN bus.| Part No. | AS8525 |
