TMR1228 Datasheet | MultiDimension

Description The TMR1222/TMR1228 series magnetic switches integrated the tunneling magnetoresistance (TMR) magnetic sensor and CMOS circuitry, which is able to detect the change of magnetic field and output high and low voltage signals for high accuracy position detection. Unlike Hall/AMR sensors, TMR sensors with extremely high resistance values allows TMR1222/1228 to achieve the supply current as low as 1.5 μA while operating in the full-time power supply mode, and maintaining the response frequency of the magnetic signal is 1 k Hz. Therefore, the TMR1222/TMR1228 can provide true continuous detection of magnetic field signals, avoiding sampling errors from the traditional time-sharing power supply mode.
