Bipolar Latch Hall ICs - BU52040HFV

Bipolar Latch Hall IC detects polarity change for S and N. The operation is more stable comparing to magnetic force detection (The duty on output pulse will be consistent). It is perfect fit as an interface to wheel key and track ball application.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
