DRESDEN, GERMANY - ZMD AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling energy-efficient solutions, today announces the ZSSC1750 and ZSSC1751, two fully automotive-qualified, high-precision data-acquisition system basis chips (SBCs).
As a global supplier of analog and mixed-signal solutions for automotive, industrial, medical, information technology and consumer applications, ZMDI introduces these new ICs to extend its battery sensing and battery management product family. Both the ZSSC1750 and ZSSC1751 include two high-precision, high-resolution analog-to-digital converters (ADCs) for simultaneous measurement of battery voltage and current as well as internal and external temperatures. In addition, they provide several power-saving operating modes, including an autonomous periodic wake-up from sleep mode that can run entirely self-contained. Once a fault condition, such as exceeding a predefined current, voltage or temperature threshold occurs, these SBCs will automatically wake up and alert a higher-level controller. Both SBCs are controlled via an SPI interface. The ZSSC1750 provides an additional communication option using a physical LIN interface.
"The ZSSC1750 and ZSSC1751 System Basis Chips are perfectly suited for precision data acquisition tasks in safety-critical environments, such as lead acid battery monitoring in automotive applications," said Josef Janisch, Global Product Manager for Multimarket Sensing Products. The two synchronous, high-resolution ADCs combined with a wide-range programmable gain amplifier allow complex battery management tasks at currents ranging from milliamperes to kiloamperes. A standard SPI interface makes these products compatible with microcontrollers of any size and type, giving customers the best options for selecting the most economical solutions for their requirements.
