The AS8515 system-in-package (SiP) introduced today by ams AG (SIX: AMS), a manufacturer of high-performance analog ICs and sensors for consumer, industrial and automotive applications, enables the implementation of a complete automotive battery measurement system when interfaced via SPI to any microcontroller.
The device is a stacked-die package consisting of a signal-processing die with two high-precision ADC channels for current, voltage and temperature measurements, and a high-voltage CMOS die providing voltage regulation, a LIN transceiver and watchdog functions. Supporting manufacturers’ ISO26262 safety standard compliance processes, the device is well suited for battery management systems (BMS) for lithium-ion batteries in electric vehicles, hybrid electric vehicles and vehicles with an internal combustion engine.
Providing precise and linear 16-bit digital outputs, the AS8515 is ideal for implementing State of Charge (SoC) monitoring in automotive batteries through measurement of open-circuit voltage and coulomb counting. The device also provides extremely accurate and linear conversion of small signals from other devices such as the pressure sensors used in a vehicle’s hydraulic, pneumatic or barometric systems.
By integrating voltage regulation and a LIN2.1 transceiver with signal-processing circuitry in a single package, the AS8515 provides a complete current and voltage measurement system that only requires the addition of a simple microcontroller and, for current measurement, a precision shunt resistor.
The bottom (signal processing) die in the AS8515 is the same die used in the AS8510 sensor interface chip, which ams introduced in January 2011. This is the automotive industry’s best-performing current, voltage and temperature sensor interface.
Offering two independent, high-resolution 16-bit ADC channels, it can measure signals from sub- micro volt up to 200 mV and measure current across a range from 1 mA to 2000A through a 100 micro Ohm shunt. All measurements are offset-free and highly linear across the device’s specified ambient temperature range (-40°C to +115°C). The two channels can be configured to measure the same input synchronously to provide a redundant design supporting functional safety.
The top die in the SiP is a system basis chip (SBC) providing voltage regulation via an LDO, a fully automotive- certified LIN 2.1 transceiver, and various system monitoring and protection features such as power-on reset and a window watchdog function.
The AS8515, together with external micro and its I/O ports, offers full flexibility to support use in lithium-ion BMS applications which require multiple interfaces to support functions such as cell balancing.
Bernd Gessner, vice-president and general manager of the automotive business unit at ams, said: “The AS8515 offers the right level of integration for automotive battery system designers, combining power management and LIN communications functions with precise and accurate current and voltage measurements. Offering an ordinary SPI interface, the AS8515 gives designers the freedom and flexibility to choose the MCU they need for their application.”
Price & Availability
The AS8515 integrated sensor interface is available for sampling now. It is priced at $7.50 for 1,000 pieces.
A demonstration board for the AS8515 is available. For further information on the AS8515 or to request samples, please visit www.ams.com/integrated-sensor-interface/AS8515.

In today's uber-connected, consumer-centric, cloud-enabled, insights-driven, multi-device, global world, the focus of solutions has shifted from the product that is sold to the person who is buying the product or service. Enterprises have rebranded their business around the consumers of their products. The buyer is the person and the focus is not on the offering. The person is connected through multiple devices, wearables, at home, on the road, and in multiple locations, sometimes simultaneously...

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the work...

WebRTC is about the data channel as much as about video and audio conferencing. However, basically all commercial WebRTC applications have been built with a focus on audio and video. The handling of “data” has been limited to text chat and file download – all other data sharing seems to end with screensharing. What is holding back a more intensive use of peer-to-peer data? In her session at @ThingsExpo, Dr Silvia Pfeiffer, WebRTC Applications Team Lead at National ICT Australia, looked at differ...
