1 Functional Diagram  
2 General Description  
The MLX90251 is  
a
CMOS Programmable,  
1
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 VOQ (VOUT @ 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 VOQ over 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.
