P4248 Low Power, Omnipolar, Hall Switch 1. General Data Sheet Rev. 1.1 Descriptions P4248 is a Hall-effect sensor integrated circuit of omni-polar switch type. It includes a hall plate, an amplifier with dynamic offset cancellation, a voltage regulator for operation with supply voltage from 1.8V to 5.5V, a sleep/awake control logic for low power consumption, schmitt trigger comparator, and a push-pull output. The offset cancellation reduces the offset voltage normally caused by device over molding, temperature dependencies, and thermal stress. The device is a temperature stable, stress-resistant sensor P4248 detects magnetic field which is perpendicular to the package in an arbitrary direction.
