ZMD AG (ZMDI) announced the ZSSC1750 and ZSSC1751, two automotive-qualified, high-precision data-acquisition system basis chips (SBCs) that extend the firm’s battery sensing and battery management product family.

The ZSSC1750 and ZSSC1751 each 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. The chips also provide several power-saving operating modes, including an autonomous periodic wake-up from sleep mode that can run entirely self-contained.

Allegro MicroSystems, LLC introduced a new Hall-effect based integrated circuit (IC) that provides a user-friendly solution for true zero-speed digital ring magnet and gear tooth sensing in two-wire applications.

Allegro’s A1688 wheel speed sensor IC targets the automotive market and contains industry leading features such as outstanding pitch deviation accuracy, consistent ICC distribution: >6 sigma, low jitter and enhanced EMC performance, and simple module assembly by utilizing a built-in cap and wider lead width/spacing.

The integrated circuit incorporates a dual-element Hall-effect circuit and signal processing that switches in response to differential magnetic signals created by magnetic encoders, or, when properly back-biased with a magnet, from ferromagnetic targets.
