The MLX90277 is a Dual Programmable 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. |
