FSH4913LAD

MICRO POWER, ULTRA-SENSITIVE HALL SWITCH FSH4913 FEATURES Micro power design Operation with North or South pole(omni polar) 2.4V to 5.5V battery operation High sensitivity and high stability of the magnetic switching points High resistance to mechanical stress Digital output signal Good RF noise immunity -40℃ to 85℃ operating temperature Packages: SOT23-3L , TSOT23-3L, SC70-3L, SIP3L and DFN6L GENERAL DESCRIPTION The FSH4913 is an Integrated Hall effect sensor designed specifically to meet the requirements of lowpower devices. e.g. as an On/Off switch in Cellular FlipPhones, 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 operate phase the IC compares the actual magnetic field detected with the internally compensated switching points. The output 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 Omnipolar, i.e. it can be switched on with either the North or South pole of a magnet.
