APX9131A

APX9131A Hall Effect Micro Switch IC Features • • • • • Micro Power Operation for Battery Applications Chopper Stabilized Amplifier Independent of North or South Pole Magnet, Easy for Manufacture Small Size Package Lead Free and Green Devices Available (RoHS Compliant) General Description The APX9131A, integrated circuit, is an ultra-sensitive, pole independent Hall-effect switch with a latched digital output. A 2.5 volt to 3.5 volt operation and an unique clocking scheme reduce the average operating power requirements, either a north or south pole of sufficient flux will turn the output on; in the absence of a magnetic field, the output is off. The polarity independence and minimal power requirement allow this device to be easily replaced reed switch for superior for signal conditioning. Advanced CMOS processing is used to take advantage of Applications • • • • Micro Switch Handheld Wireless Application Wake Up Switch Clamp Shell Type Application Switch Magnet Switch in Low Duty Cycle Applications low-voltage and low-power requirements, SOT-23 package provided a optimized package for most applications.

ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by weight). ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
