Microchip’s Innovation in Automotive Thermal Management

Introduction to Microchip’s MCP998x Temperature Sensors

Microchip Technology has introduced the MCP998x series, a groundbreaking family of remote temperature sensors designed specifically for automotive applications. Recognizing the scarcity of multi-channel temperature sensors in the market, this new product line stands out as one of the most extensive automotive-grade, multi-channel temperature sensor portfolios. The MCP998x series ensures remarkable precision, boasting 1°C accuracy across a broad operational temperature range. Each sensor in this family, consisting of five different models, features non-overwritable shutdown temperature setpoints to enhance security and prevent potential software or malicious tampering.

Advanced Features and Design Simplification

The MCP998x series goes beyond standard monitoring with up to five channels for temperature supervision and multiple alert and shutdown options for enhanced security. These sensors incorporate advanced features like resistance error correction and beta compensation, which negate the need for additional configurations and promote heightened accuracy. By monitoring several thermal points through a single integrated sensor, the MCP998x not only minimizes board complexity but also significantly reduces overall design size. This simplification leads to a more streamlined bill of materials, optimizing both cost and efficiency in automotive designs.

Extending Choices for Customers

Fanie Duvenhage, the Vice President of Microchip’s Mixed-Signal and Linear Unit, highlights the MCP998x family’s contribution to widening customer choices in a traditionally limited product field. The MCP998x family, with its ten different devices, offers unparalleled accuracy, especially in high-temperature environments up to 125°C. Additionally, five of these sensors come equipped with enhanced shutdown safety features, providing a diverse range of options for automotive multi-channel temperature monitoring.

High-Temperature Tolerance and Application Versatility

The MCP998x sensor family excels in high-temperature applications, maintaining 2.5°C accuracy up to 125°C. This high-temperature endurance is especially beneficial in automotive settings where electronic components are exposed to extreme temperatures. The versatility of the MCP998x sensors makes them suitable for various vehicle functions, including HID lamps, advanced driver-assistance systems (ADAS), automotive servers, video processing, infotainment systems, engine control, telematics, and body electronics like seat control, lighting systems, mirror control, and power windows.
