1 . description the HED57XXU12 omnipolar hall effect sensor ic is fabricated on mixed signal cmos technology. it incorporates advanced dynamic offset cancellation techniques to provide accurate and stable magnetic switch points. the circuit design provides an internally controlled clocking mechanism to cycle power to the hall element and analog signal processing circuits. this serves to place the high current-consuming portions of the circuit into a sleep mode. periodically the device is awakened by this internal logic and the magnetic flux from the hall element is evaluated against the predefined thresholds. if the flux density is above or below the b op /b rp thresholds then the output transistor is driven to change states accordingly. while in the sleep cycle the output transistor is latched in its previous state. the design has been optimized for service in applications requiring ext ended operating lifetime in battery powered systems. the output transistor of the HED57XXU12 is switched on (b op ) in the presence of a sufficiently strong south or north magnetic field. the output is switched off (b rp ) in the absence of a magnetic field. 2. specification 2.1 absolute maximum ratings ? supply voltage, v dd : :5v output voltage, v out :5v output current, i out :10ma operating temperature range (t a ): -40 ? to 85 ? ? storage temperature range (t s ):-55 ? to +150 ? esd sensitivity : mm 500v, hbm 5000v exceeding the absolute maximum ratings may cause fatal damage. 2.2 HED57XXU12 electrical specification [operating conditions ta=25c, v dd =2.5v to 3.5v] parameter symbol test conditions min. typ. max. units supply voltage v dd operating 2.5 2.75 3.5 v supply current i dd awake, v dd =3.5v - 3.0 5.0 ma i sl sleep, v dd =3.5v - 3.5 6.0 ? i avg average, v dd =3.5v - 6.5 10.0 ? low level output voltage v low b>b op ,i out =1ma 0.0 0.25 0.4 v output leakage current i leak bHED57XXU12(060919) rev.0 page 3/17
