XT4913
XT4913 is High Sensitivity CMOS Hall IC manufactured by Silinktek.
Low Current Consumption, High Sensitivity CMOS Hall IC
- General Description
The XT4913 is an integrated hall-effect sensor 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-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 pares the actual magnetic field detected with the internally pensated 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.
