The MLX90248 is a bipolar hall effect sensor IC fabricated from mixed signal CMOS technology and incorporates advanced chopper stabilization techniques to provide accurate and stable magnetic switch points.
The circuit design provides an internally controlled clocking mechanism to cycle power to the hall element and analog signal processing circuits. This serves to place the high current-consuming portions of the circuit into a "sleep" mode. Periodically the device is "awakened" by this internal logic and the magnetic flux from the hall element is evaluated against the predefined thresholds.
If the flux density is above or below the thresholds then the output transistor is driven to change states accordingly. While the device is in the "sleep" cycle the output transistor is latched in its previous state. The design has been optimized for use in applications requiring extended operating lifetime in battery powered systems.
The output transistor will be latched ON in the presence of a sufficiently strong South-pole or North-pole magnetic field facing the marked side of the package. The output transistor will be latched OFF in the absence of a magnetic field.
