OH9213 Series Omnipolar CMOS Hall IC
1. General Description
OH9213 series IC is an integrated hall-effect sensor explicitly designed to meet the requirements of lowpower devices, for example, as an On/Off switch in Cellular Flip-Phones, with battery operating voltages of 2.4V-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 operating phase, the IC pares the actual magnetic field detected with the internally pensated switching points. The output Q is switched at...
