AH8115 Datasheet | AiT Semiconductor

Ai T Semiconductor Inc. .ait-ic. HALL SWITCH LOW CURRENT CONSUMPTION, HIGH SENSITIVITY CMOS HALL IC DESCRIPTION Features The AH8115 is an integrated hall-effect sensor designed specifically to meet the requirements of low-power devices. e.g. as an On/Off switch in cellular flip-phones, with battery operating voltages of 2.0V-5.5V. Precise magnetic switching points and high temperature stability are achieved through the unique design of the internal circuit. An onboard clock scheme is used to reduce the average operating current of the IC. During the operate phase the IC pares the actual magnetic field detected with the internally pensated switching points. The output Q is switched at the end of each operating phase. During the Stand-by phase the output stage is latched and the current consumption of the device reduced to some μA. The IC switching behaviour is omnipolar, it can be switched on with either the north or south pole of a magnet. AH8115 is higher sensitivity of magnetic induction than AH8113, it can be used in security systems、 sensing magnet smaller occasions. - Micro power design - 2.0V to 5.5V battery operation - High sensitivity and high stability of the magnetic switching points - High resistance to mechanical stress - Digital output signal - Switching for both poles of a magnet (omnipolar) - Not suitable for automotive application - Operating temperature range - TMIN ≤ TA ≤ TMAX - 40°C ≤ TA ≤ 85°C - Operating voltage range 2.0V ≤ VDD ≤ 6.0V - Available in TSOT-23 Package APPLICATION - Mobile phones - Notebook - Portable electronic devices TYPICAL APPLICATION The AH8115 is available in TSOT-23, package.
