AH9246 ULTRA HIGH SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments NEW PRODUCT The AH9246 is an ultra high sensitivity Hall-effect switch with internal pull-up resistor on the output, designed for battery operated handheld equipments to industrial applications. (Front View) A chopper stabilized architecture improves stability of magnetic switch points over the whole operating range. A sleep-awake logic controls the sleep and awake time to reduce the average operating current of the device. During the awake time, the output is changed with the magnetic flux density. During the sleep time, the output is latched in its previous state and the current consumption reduces to 4µA typical at 3V. The average current consumption is 8µA at 3V. 3 OUTPUT 2 GND 1 VDD TO92S The output can be switched on with either north or south pole of sufficient strength. If the magnetic flux density perpendicular to the part marking surface is larger than operating point (BOP), the output will be turned on; if it is less than releasing point (B RP), the output will be turned off. (Top View) GND The AH9246 is available in industry standard TO92S and SC59 packages. 3 Features Omnipolar Operation (Switching with North or South Poles) Micropower Operation Built in Pull-up Resistor on the Output 2.5V to 5.5V Power Supply Stabilized Chopper Superior Temperature Stability Digital Output Signal -40°C to +85°C Operating Temperature ESD (HBM): 5000V Small Low Profile Industry Standard SC59 and TO92S Packages Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Notes: 1 2 VDD OUTPUT SC59 Applications Cover Switch in Notebook PC/PDA Handheld Wireless Application Awake Switch Magnet Switch in Low Duty Cycle Applications 1.

Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. 5. The absolute maximum VDD of 7V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to operate the device at the absolute maximum rated conditions for any period of time. 6. Electronic semiconductor products are sensitive to Electro Static Discharge (ESD). Always observe Electro Static Discharge control procedures whenever handling semiconductor products.
