OH4913 Omnipolar CMOS Hall IC
1. General Description
OH4913 IC is an integrated hall-effect sensor designed to meet the requirements of low-power devices, for example, as an On/Off switch in Cellular Flip-Phones, with battery operating voltages of 1.65V to 5.5V. The IC switching behavior is Omnipolar, and it can switch on with either the North or South pole of a magnet. An onboard clock scheme reduces the average operating current of the IC. During the operating phase, the IC compares the actual magnetic field detected with the internally compensated switching points. The output voltage is switched at the end of each operating phase. During the Stand-by phase, the output stage is latched, and the current consumption reduces to some μA.
