GENERAL DESCRIPTION
e.g. as an On/Off switch in Cellular Flip-Phones, with battery operating voltages of 1.65V-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 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 of the device reduced to some µA. The IC switching behavior is Omni polar; it can be switched on with either the North or South pole of a magnet.● Typical Application Circuit 10K
