MICRO POWER, ULTRA-SENSITIVE HALL SWITCH FSH4913 GENERAL DESCRIPTION FEATURES z z z z z z z z z 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. 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 FUNCTIONAL BLOCK DIAGRAM VDD Awake & Sleep Timing Logic VOUT Dynamic Offset Cancellation Hall Plane Chopper Amplifier Hysteresis Latch GND TYPICAL APPLICATION 3 GND + FSH4913 0.1uF VDD VOUT 1 2 Output R=51K 1/10 2007-7-19 MICRO POWER, ULTRA-SENSITIVE HALL SWITCH FSH4913 PIN CONFIGURATION (1) SOT23-3L/TSOT23-3L/SC70-3L (Top View) (2) SIP3L (Top View) (3) DFN6L (Top View) GND 3 1 2 VDD VOUT Pin SOT23/TSOT23/SC70 1 2 3 SIP3L 1 3 2 DFN6L 1 3 5 2 4 6 3 VOUT 2 GND 1 VDD Symbol VDD VOUT GND NC NC NC Function Supply Voltage Signal Output (Open Drain) Ground Not Connected Not Connected Not Connected ABSOLUTE MAXIMUM RATINGS Parameter Symbol Maximum Supply Voltage VDD 5.5 Supply Current IDD 2.5 Output Voltage VO 5.5 Output Current IO 1 Operating Temperature Range TA -40 to 85 Junction Temperature TJ -40 to 150 Storage Temperature TSTG -40 to 150 Magnetic Flux Density B unlimited Power Dissipation PD 230 Note: Stress above the listed absolute maximum rating may cause permanent damage to the device OPERATING RANGE Parameter Symbol Min.
