5. General Description
The Melexis MLX90290 is a Second Generation linear
Hall-effect sensor designed in mixed signal CMOS
technology.
The device is offered in a RoHS compliant Thin Small
Outline Transistor (TSOT) for surface mount and UA
(TO-92) for Pin Through Hole mount.
The device integrates a voltage regulator, Hall sensor
with advanced offset cancellation system and an
analog output driver, all in a single package.
The Output voltage is proportional to the applied
magnetic field and to the chip supply voltage
(ratiometric).
The Output Offset Level (Quiescent Level) at zero
magnetic field equals to 50% of the chip supply voltage.
