2 General Description

The MLX90251 is

CMOS Programmable,

Supply

Ratiometric Linear Hall Effect sensor IC. The

linear output voltage is proportional to the

magnetic flux density. The ratiometric output

voltage is proportional to the supply voltage. The

MLX90251 possesses active error correction

circuitry, which virtually eliminates the offset errors

normally associated with analog Hall Effect

devices. All the parameters of the MLX90251

transfer characteristic are fully programmable.

The V_OQ(V_OUT@ B = 0 Gauss), the Sensitivity,

the slope polarity, the Output Clamping levels, the

thermal Sensitivity drift, the internal bias point and

a low-pass filter are all programmable in end-user

applications. The MLX90251 has a very stable

thermal compensation for both the Sensitivity and

the V_OQover a broad temperature range. For

traceability purpose the MLX90251 will carry a

unique ID number programmed by Melexis and 24

bits of EEPROM memory are allocated for a user

programmed serial number.
