| 供应全极性微功耗霍尔开关YH4913 TO-92 |
The YH4913 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 mechanism to cycle
power to the Hall element and analog 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
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.
Features
2.4V-5.5V battery operation
High sensitivity and high stability of the magnetic switching
High resistance to mechanical stress
Digital output signal
