TLE4913HTSA1

TLE4913HTSA1 is a low-power, integrated hall-effect switch sensor. It is 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 2.4V to 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 compares the actual magnetic field detected with the internally compensated 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 is reduced to some µA. The IC switching behaviour is Omnipolar, i.e. it can be switched on with either the North or South pole of a magnet.
