Description
TMR130x is an omnipolar magnetic switch integrated
the tunnel 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 TMR130x
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 greater than 1 kHz. Therefore, TMR130x
can provide true continuous detection of magnetic
field signals, avoiding sampling errors from the
traditional time-sharing power supply mode.
TMR130x allows a wide range of operating supply
voltages from 1.8 V to 5.5 V with excellent temperature
characteristics, and can meet the requirements of
most applications.
TMR130x is available in three compact SOT23-3,
TO92S and LGA3L (2 mm × 1.5 mm × 0.63 mm)
packages.
