my country, December 12, 2012 - Austrian Microelectronics (Six Stock Code: AMS) is the world's leading high-performance simulation IC and sensor chip manufacturer, specializing in consumption, industrial, automotive applications industry, the company Today announced the launch system level package (SIP) chip as8515. When connecting to any microcontroller through the SPI interface, new products can help achieve intact automotive battery measurement systems. The AS8515 is a stacked product encapsulated product comprising two high-precision ADC channels for measuring current, voltage and temperature signal processing crystal, a high pressure CMOS crystal and one LIN transceiver and a Lin transceiver and Monitoring function.

The product will support manufacturers to meet the requirements of ISO26262 safety standards, and is ideal for electric vehicles, hybrid vehicles and internal combustion engine vehicles that use lithium-ion batteries (BMS). The AS8515 supplies precise and linear 16-bit digital output is an ideal choice for monitoring the electricity state (SOC) in automotive batteries through open circuit voltage and Coulomb Count. The new product also provides accurate and linear conversion for other small signals such as pressure sensors for vehicle hydraulic, pneumatic or air pressure systems.

By integrating a regulator function and a LIN2.1 transceiver having a signal processing circuit in a single-chip package, the AS8515 supplies a complete current and voltage monitoring system, and as long as a simple microcontroller and precision diversion required for current measurement Resistor. The AS8515 uses the same bottom (signal processing) crystal of the AS8510 sensor interface chip introduced in January 2011 in January 2011.

This is the best current, voltage and temperature sensor interface for the automotive industry. The new product has two independent, high-resolution 16-bit ADC channels, can measure the highest 200mV voltage signal and current in the range of 1mA to 2000A via 100 microol splitter. Within the predetermined ambient temperature range (-40 ¡ã C to + 115 ¡ã C), all measurements are non-deviation and highly linear.

These two channels can be configured in synchronization to measure the same input circuit, thus providing redundant design for functions. The upper crystal element in the SIP is a system base chip (SYSTEMBASISCHIP), supplies regulatory functions by low pressure difference linear regulator (LDO), and includes automotive-level LIN2.1 transceivers and a variety of power reset and windows.

System monitoring and protection function of monitoring. The AS8515 is combined with external micro and I / O interfaces, which can be flexibly used in a lithium-ion battery management system application that supports functions such as electricity balancing. Berndgessner, vice president and general manager of the Austrian Microelectronics Business Department, said: "AS8515 is the integration of automotive battery system designers, combined with power management and LIN communication function with precision, accurate current and voltage measurement.

The ordinary SPI interface supplied by the AS8515 makes the designer according to the application needs freedom, flexibly select the required microcontroller. "Price and Supply AS8515 Integrated Sensor Interface Now Sample. Technical support AS8515 demo board is now available.
