MDT's TMR1370 ultra‑low‑power magnetic switch enables over two years of standby operation in continuous glucose monitors, extending battery life for wearable medical devices
Executive summary: MDT unveiled the TMR1370 magnetic switch IC, stating it can sustain >2 years of standby in CGM devices with a max supply current of 50 nA. Longer standby reduces battery‑related maintenance costs and improves patient compliance for continuous glucose monitoring, a fast‑growing segment of wearable health tech.
Who is involved: MultiDimension Technology Co., Ltd. (MDT) as the developer; potential customers include medical device manufacturers that produce CGM systems.
Likely next: MDT will likely seek qualification and design‑win engagements with CGM makers, followed by volume production ramp‑up later in 2026.
The announcement highlights MDT’s latest TMR1370 IC, which draws a maximum supply current of just 50 nA, allowing CGM devices to remain idle for more than 24 months without battery replacement. This advance addresses a key pain point in wearable health tech—frequent recharging or battery swaps—and could strengthen MDT’s position in the low‑power sensor market. While the technical details are clear, the commercial impact will depend on adoption by device makers and any required regulatory clearances.
