供应微功耗霍尔开关YH4913
信息内容：Low Power Hall Switch YH4913 GENERAL DESCRIPTION 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 ...
