TMR Digital Magnetic Switches

Littelfuse TMR Digital Magnetic Switches integrate TMR and CMOS technology and are available in bipolar or omnipolar versions. These switches feature a TMR magnetic sensor and CMOS signal processing circuitry within the same package, including an on-chip TMR voltage generator for precise magnetic sensing. The LF11215TMR bipolar switch draws only 1.5µA, while the LF21112TMR omnipolar switch draws 200nA, resulting in low power operation for both models. Additional features include a fast response time, accurate switching points, excellent thermal stability, and an SOT23-3 package. The output of these switches goes low (turns on) when the magnetic field parallel to the sensing axis exceeds the operating point threshold, BOP. However, when the magnetic field is lowered below the release point BRP, the device output switches high (turns off). Littelfuse TMR Digital Magnetic Switches are suitable for speed sensing, proximity switches, utility meters, and rotary and linear position sensing.

Portable Medical Devices & Connected Drug Delivery

Littelfuse Portable Medical Devices and Connected Drug Delivery Systems feature a range of products ideal for use in wearables, digital hearing aids, insulin pumps, blood pressure monitors, and connected pharmaceutical delivery devices such as auto-injectors and inhalers. Portable and connected devices are changing how medical services are delivered to patients. These connected healthcare products from Littelfuse help lower healthcare costs, improve efficiency, and empower patients.

TMR Switches

Littelfuse TMR Switches are digital magnetic switches that integrate tunneling magnetoresistance (TMR) and CMOS technology. This technology provides a magnetically triggered digital switch with high sensitivity, and ultralow power consumption. This Littelfuse series contains a TMR magnetic sensor and CMOS signal processing circuitry within the same package. An on-chip TMR voltage generator is also included for precise magnetic sensing. A TMR voltage amplifier and comparator plus a Schmitt trigger provide switching hysteresis for noise rejection.
