ENS170A Automotive-Grade Air Quality / Multi-Gas Sensor Array

ENS170A Automotive-Grade Air Quality / Multi-Gas Sensor Array

The ENS170A is an automotive-grade, micro-machined, multi-gas / air quality sensor ASIC with integrated Arm Cortex-M0 CPU. 

Besides detection of reducing and oxidizing gases, it features superior processing power plus LIN-, I2C-, SPI- or PWM-slave interface. Its additional I2C-master renders control of further I2C slave devices, such as actuators or humidity and pressure sensors. In such combo modules the ENS170A can function as main controller, thereby significantly contributing to total BOM cost reduction.

With its multi-gas sensor array the ENS170A is ideally suited for air quality applications, as well as Li-Ion battery condition monitoring and thermal runaway detection. Its small package allows tiniest automotive modules and qualifies for direct board integration in battery management systems and balancers of battery electric vehicles or stationary battery solutions.
