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.
