The MCP998x family is one of the most extensive portfolios of automotive-grade remote temperature sensors offered by a single vendor.
Effective thermal management plays a crucial role in automotive design. However, unlike numerous other components, there is a noticeable shortage of choices for multi-channel remote temperature sensors. Microchip Technology addresses this gap by introducing the MCP998x family, consisting of 10 automotive-qualified remote temperature sensors. This family is one of the most extensive portfolios of automotive-grade multi-channel temperature sensors available. Within this device family, five sensors feature shutdown temperature setpoints that resist being overwritten by software or intentionally disabled, enhancing their reliability and security. The key features include:
- Accuracy of 1°C
- AEC-Q100 Grade 1 qualification
- Shutdown options set by resistors, resistant to software overwriting
- Resistor error correction to eliminate resistance along long PCB traces
- Supply voltage range of 1.7V to 3.6V
Featuring the capability to monitor up to five channels and offering various alert and shutdown options for enhanced security, this product family is well-equipped to support systems overseeing multiple thermal elements. The integrated remote sensors also incorporate resistance error correction and beta compensation, eliminating additional configuration necessary to achieve improved accuracy. This product reduces board complexity and size by enabling the monitoring of temperatures at multiple locations through a single, integrated temperature sensor, simplifying the design process and resulting in a more cost-effective bill of materials (BOM).
Notably, the device family is designed for increased accuracy, achieving 2.5°C accuracy up to 125°C, surpassing challenges faced by many competitors at the high end of the traditional temperature range. This elevated temperature tolerance makes them well-suited for automotive applications where electronics’ operating temperatures are a critical consideration. The MCP998x sensors are tailored to support various vehicle functions, including HID lamps, advanced driver-assistance systems (ADAS), automotive servers, video processing, infotainment systems, engine control, telematics, and body electronics such as seat control, lighting systems, mirror control, and power windows.
The family is complemented by the new EV23P16A evaluation board for simplified design and development. Regarding pricing and availability, the family of multi-channel temperature sensors is accessible starting at $0.63 each in 10,000-unit quantities.
The family of multi-channel temperature sensors finds application in a diverse range of automotive functionalities. These include infotainment systems, encompassing radio and LCD screens, as well as side-view mirrors, diagnostics, engine control, and High-Intensity Discharge (HID) lamps. Additionally, the sensors support Advanced Driver-Assistance Systems (ADAS), automotive servers, graphics and video processing, telematics, and various aspects of body electronics. From managing HVAC systems to ensuring the optimal performance of a broad spectrum of automotive components, the MCP998x family caters to various applications within the automotive industry.
