AS8515-ZMFP

Overview

The AS8515-ZMFP is a stacked-die system-in-package designed for 12V battery sensor applications. It integrates a high-voltage Top die for power management and LIN 2.1 transceiver functions with a low-voltage Bottom die for sensor interface operations within a 32-pin MLF (5x5 mm) package. The device features two independent ADC channels capable of measuring shunt current signals up to ±160 mV versus ground via a programmable gain amplifier, or larger signals in the 1V range without amplification. It provides a regulated 3.3V supply for external microcontrollers and communicates with ECUs through a LIN 2.1 transceiver.

Feature Summary

• Integrated LIN 2.1 transceiver with slew-controlled bus driver for electromagnetic emission control
• Dual independent ADC channels with programmable gain amplifier and offset auto-zero architecture
• Stacked die system providing high-voltage power management and low-voltage sensor interface
• Internal reverse polarity protection and load dump protection for automotive robustness

Applications

• Battery sensors with shunt current sensors at the negative pole
• Lead acid, AGM, and Li-Ion battery monitoring systems
• General purpose sensor interfaces for automotive LIN slaves

Procurement Notes

Verify the specific ordering suffix ZMFP against official manufacturer documentation to confirm exact packaging configuration and reel specifications. Ensure compatibility with the required 32-pin MLF footprint during PCB layout. Confirm that the component meets all necessary automotive qualification standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when simultaneous measurement of shunt current and battery voltage is required in a single integrated solution. It is suitable for lead acid, AGM, and Li-Ion batteries up to 18V nominal with 42V overvoltage capability. Consider the integrated LIN 2.1 transceiver if direct communication with an ECU is needed without additional discrete components.

Part Context

The AS8515 belongs to a family of data acquisition systems combining power management with sensor interfacing. It utilizes a stacked die technology to house both high-voltage and low-voltage circuits in a compact form factor. This integration reduces board space and simplifies design by consolidating analog front-end, digital processing, and communication interfaces into one package.
