customers to obtain the latest version of relevant information to verify before placing orders.

High Sensitivity Hall Effect Sensor IC with Reverse Voltage Protection

The APX9141 is an integrated Hall Effect Sensor IC de-

signed for electric commutation of DC brushless motor

applications. The APX9141 still can operate at as low as 3

volts. The APX9141 is available in low cost TO-92M4 pack-

age with 3 different magnetic ranks.

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-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).
