The TMR1370 expands the company’s existing sensor lineup, building on the architecture of previous models like the TMR1367 and TMR1369. By utilizing proprietary Tunneling Magnetoresistance technology, the device achieves a typical power draw of 30nA at a 3V supply. This reduction in energy consumption is critical for medical wearables, where battery capacity must be preserved for active monitoring cycles after the device has been stored on a shelf.
MDT Unveils TMR1370 Sensor to Extend CGM Battery Life
Continuous glucose monitoring devices can now remain in standby mode for over two years, thanks to a new ultra-low-power magnetic switch from MultiDimension Technology. The TMR1370 chip, which draws a maximum of 50nA, aims to solve power constraints in wearable medical hardware by prioritizing long-term energy efficiency.
Designed for integration into compact systems, the switch operates within a 1.8V to 4.0V range and features a maximum operating point below 40 Gauss. The sensor is housed in a miniature 1.6×1.6×0.5mm DFN5L package, allowing for thinner, lighter medical devices. System designers can now choose between X-axis and Z-axis configurations to better suit various mechanical layouts. Samples are currently available for purchase through DigiKey and the manufacturer's website.
