System basis chips suit safety-critical environments

The devices 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, the SBCs will automatically wake up and alert a higher-level controller. Both devices are controlled via an SPI interface. The ZSSC1750 provides an additional communication option using a physical LIN interface.

“The ZSSC1750 and ZSSC1751 SBCs are 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, Multimarket Sensing Products, ZMDI. 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 MCUs of any size and type, giving customers the best options for selecting the most economical solutions for their requirements.

Both ZSSC1750 and ZSSC1751 are in full production. Parts and evaluation kits are available from ZMDI. For 1,000 pieces, the ZSSC1750 is priced at $5.67 per unit and the ZSSC1751 is priced at $5.47 per unit.
