| HALL EFFECT SENOR IC | MAGNETIC SENSOR | OH41F Hall Latch IC 1. General Description OH41F Hall sensor IC latch on to a first pole (North or South) until a magnetic field of sufficient strength of the opposite polarity is near the sensor IC. They internally consist of a reverse voltage protection device, voltage regulator, Hall voltage generator, a differential amplifier, Schmitt trigger, and the open collector output level. On-board regulation provides stable operation over a 4Vdc to 30 Vdc supply voltage range. These sensors are capable of continuous 20 m A sinking output and maybe cycled as high as 50 m A max. The digital, open collector sinking-type output is easily interfaced with a wide variety of electronic circuits. Flat TO-92S, SOT89, and SOT23 package style are available. 2. Features - 4V to 30V DC operation voltage - Open-Collector sinking type - 50m A maximum sinking output current. - Reverse Polarity Protection - Good temperature performance 3. Applications - The brushless DC motor internal reversing - The motor speed and direction detection - The motor of the electric bicycle, power-assisted device - Speed sensor, counter - The flow sensor, flow meter - The automotive odometer, speed sensor 4.
