Supply  
Ratiometric Linear Hall Effect sensor. Two  
discrete CMOS ICs are mounted inside a single  
package, electrically insulated, and independently  
programmable. The MLX90277 is suitable for  
applications requiring full redundancy. The linear  
output voltages are proportional to the magnetic  
flux density. The ratiometric output voltages are  
proportional to the supply voltages. The  
MLX90277 possesses active error correction  
circuitry, which virtually eliminates the offset errors  
normally associated with analog Hall Effect  
devices. All the parameters of the MLX90277  
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 MLX90277 has a very stable  
thermal compensation for both the Sensitivity and  
the VOQ over a broad temperature range. For  
traceability purpose the MLX90277 will carry a  
unique ID number programmed by Melexis and 24  
bits of EEPROM memory are allocated for a user  
programmed serial number.
