功耗霍尔传感器  全极性霍尔丝印：13S 013 贴片23

Functional Description 

The  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 ñ 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 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 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
