技术问答

MDT's (MultiDimension Technology) TMR1102 is a unipolar magnetic switch specially designed and developed for applications which require high speed, high sensitivity and high accuracy detection while meeting low power consumption requirements.

TMR1102 integrates the high accuracy push-pull tunnel magnetoresistance (TMR) magnetic sensor and CMOS circuitry including an on-chip TMR voltage generator, comparator, Schmitt trigger and CMOS output, which is able to detect the change of magnetic field and output high and low voltage signals based on a preset threshold level. An internal band gap regulator is used to provide temperature compensated supply voltage for internal circuits, and it allows a wide range of operating supply voltages from 1.8V to 5.5V.

TMR1102 is an ideal solution for many low-power, high-performance applications with micro-ampere level supply current, higher response frequency, a wide operating temperature range, and excellent anti-magnetic interference characteristics. It is available in packaging form factors of SOT23-3 (P/N: TMR1102S).
