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 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. - FUNCTIONAL BLOCK DIAGRAM Awake & Sleep Timing Logic VOUT Hall Plane Dynamic Offset Cancellation Chopper Amplifier Hysteresis Latch GND - TYPICAL APPLICATION 3 GND + 0.1u F VDD 1 VOUT 2 Output R=51K 1/10 2007-7-19 MICRO POWER, ULTRA-SENSITIVE HALL SWITCH - PIN CONFIGURATION (2) SIP3L (Top View) (3) DFN6L (Top View) 3 2 1 VOUT GND VDD (1) SOT23-3L/TSOT23-3L/SC70-3L (Top View) VOUT ..
