FD2H002BYR-G1

FD2H002Ba/FD2H002BY/FD2H002BH Low-Power Hall Switch General Description FD2H002B is a low-power integrated Hall switch designed to sense the applied magnetic flux density and give a digital output, which indicates the present condition of the magnitude sensed. One example of the applications is the on/off switch in cellular flip-phones. The micro power design is especially suitable for battery-operated systems such as cellular phones or laptop computers, in which power consumption is one major concern. The typical power consumption of FD2H002B is below 10μW at 2.7V. The magnetic switching points are precise and insensitive to process and temperature variations. For FD2H002B, the output will be at the “low” level if the applied magnetic flux density is stronger than the switching threshold. For detailed magnetic flux direction please refer to the figure.3.

These current sources in turn guarantee proper operation of the chip and precise switching thresholds under all kinds of environments specified in the specification.  Oscillator + Sequencer The built-in oscillator provides the clock signal, which is taken by the sequencer to determine the periods of the operating phase and the stand-by phase. Typically the operating time is about 60us and the stand-by time is 150ms. Using such a clocking scheme, the average power consumption is almost equal to that in the stand-by phase, which is under 10μW at 2.7V.  Power on Reset Used to detect the power-up ramp and reset the digital circuits to attain correct operation as soon as the power is ready.  Chopper Amplifier To achieve a higher resolution the chopper amplifier structure is adopted in this design. Use of this structure dynamically removes both the offset and flicker noise at the same time.  Hysteresis Control This block determines the switching threshold of the Hall switch in different situations.
