Automotive temperature sensors provide multichannel thermal control

Mouser now stocks Microchip Technology's MCP998x automotive temperature sensors. This family of AEC-Q100 grade 1 qualified multichannel sensors measures temperatures with 1C accuracy up to 85C and 2.5C up to 125C. The sensors deliver precise heat control in automotive applications, including infotainment systems, engine controls, diagnostics, and side-view mirrors.

The automotive temperature sensors support accurate thermal monitoring across up to five channels. Integrated resistance error correction and beta compensation provide reliable temperature measurements without additional configuration. With up to five channels of monitoring and several alert and shutdown options for security, this product family can support systems that supervise more than one thermal element. The remote sensors also integrate resistance error correction and beta compensation, eradicating the need for additional configuration for improved accuracy. Monitoring temperatures at multiple locations with a single, integrated temperature sensor reduces board complexity and size, and simplifies design for a lowered BOM.

The sensors, one of the largest portfolios of automotive-grade multichannel temperature sensors in the industry, provide superior accuracy at the higher temperatures expected in demanding automotive applications. Also, the sensors' 1.7V to 3.6V supply voltage range ensures compatibility with various systems. Resistor-driven setpoints protect critical shutdown temperatures from malicious software overrides.

The sensors are supported by the EV23P16A evaluation board, also available from Mouser. The evaluation board incorporates a pre-mounted target device and easy connection to a PC through a USB interface. Temperature can be data-logged using the Microchip Thermal Management software GUI. The board also has onboard connectors to allow for diode-connected transistors used for offboard temperature measurements. The evaluation board lets users easily evaluate many custom programmable features such as temperature alert limit settings, temperature conversion rate, REC and power modes.
