Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which

are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D 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).

Ordering and Marking Information

The APX9131, 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

s c h e m e r e d u c e t h e a v e r a g e o p e r a t i n g p o we r

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

low-voltage and low-power requirements, SOT-23-3,

TSOT-23-3, and TO-92M3 packages provided an optimized

package for most applications.
