MLX90215 - Precision Programmable Linear Hall Effect Sensor

The MLX90215 is a Programmable Linear Hall Effect sensor IC fabricated utilizing silicon-CMOS technology. It possesses active error correction circuitry which virtually eliminates the offset errors normally associated with analog Hall Effect devices.

All magnetic response functions of the MLX90215 are fully programmable for even greater versatility. The Voq (Vout @ B=0), sensitivity, direction of slope and the magnitude of sensitivity drift over temperature, are all programmable.

The ratiometric output voltage is proportional to the supply voltage. When using the supply voltage as a reference for an ADC, fluctuations of ±10% in supply voltage will not affect accuracy. The MLX90215 has a sensitivity drift of less than +1% error, and Voq stability drift of less than +0.4% error, over a broad temperature range.

When programmed for a conventional sensitivity (with a positive gain), the voltage at the output will increase as a South magnetic field is applied to the branded face of the MLX90215. Conversely, the voltage output will decrease in the presence of a North magnetic field.

The MLX90215 programming is done through the output pin, by changing supply voltage levels. The VDD is raised to approximately 13V and 18V during programming and therefore any connected component must also tolerate this voltage excursion. PTC-04 is the proprietary programmer for the MLX90215.

The MLX90215LVA is a SIP-4 Precision Programmable Linear Hall Effect Sensor rated for -40°C to 150°C operating temperature range.
