原厂长期供应 手电筒霍尔开关、YH13S、微功耗霍尔开关

The YH13s omnipolar Hall effect sensor IC is fabricated from mixed signal CMOS

technology .It ncorporates advanced chopper-stabilization techniques to provide accurate

and stable magnetic switch points.

     The circuit design provides an internally controlled clocking mechani* to cycle

power to the Hall element and *og signal processing circuits. This serves to place

the high current-consuming portions of the circuit into a “Sleep” mode. Periodically the

device is “Awakened” by this internal logic and the magnetic flux from the Hall element

is evaluated against the predefined thresholds. If the flux density is above or below the

Bop/Brp thresholds then the output transistor is driven to change states accordingly.

While in the “Sleep” cycle the output transistor is latched in its previous state. The

design has been optimized for service in applications requiring extended operating

     The output transis or of the YH13s will be latched on (Bop) in the presence

of a sufficiently strong South or North magnetic field facing the marked side of the

package. The output will be latched off (Brp) in the absence of a magnetic field.
