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 10W 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. Features Micro power consumption 2.4V to 5.5V battery operation Chopper Amplifier based design: Insensitive to noise and offset caused by process variations, operating temperatures and mechanical stress Digital output CMOS process Available in SOT-23L/ TSOT-23L / SIP-3L package This datasheet contains new product information.
