MDT Introduces TMR1370: Ultra-Low-Power Magnetic Switch IC

MultiDimension Technology Co., Ltd. (MDT), a renowned leader in magnetic sensors and an innovator in Tunneling Magnetoresistance (TMR) technology, has unveiled the TMR1370 ultra-low-power magnetic switch Integrated Circuit (IC). This new product stands as a vital expansion of MDT's magnetic sensing lineup, specifically designed to enhance continuous glucose monitoring (CGM) devices.

Advancements in Sensor Technology

The TMR1370 builds upon the successes of its predecessors, the TMR1367, TMR1368, and TMR1369, showcasing remarkable advancements in power consumption and voltage compatibility. With a maximum supply current of only 50nA and a typical value of approximately 30nA at a 3V power supply, the TMR1370 promises ultra-low energy usage. Its efficiency is significantly beneficial for battery-powered CGM devices, allowing for more than two years of standby operation.

MDT’s continuous glucose monitoring systems greatly benefit from the magnetic wake-up mechanism, which effectively utilizes the IC's abilities to ensure longevity and reliability in medical applications. This enhances the product shelf life while preserving battery capacity, which becomes crucial for ongoing glucose monitoring post-activation.

The Technology Behind the TMR1370

The exceptional power efficiency of the TMR1370 results from MDT’s proprietary TMR technology platform, which integrates advanced magnetic sensor design with optimized device architecture and state-of-the-art wafer process technology. The IC boasts high magnetic sensitivity while ensuring ultra-low power consumption, making it ideal for modern healthcare applications.

In addition to enhancing MDT’s existing X-axis and Z-axis CGM magnetic switch range, the TMR1370 offers designers added flexibility in optimizing sensor orientation and mechanical layouts across a variety of CGM architectures, facilitating a smooth transition from earlier device generations.

Key Features of the TMR1370
