General Discription

The SS1881 is a bipolar Hall effect sensor IC fabri-

cated from mixed signal CMOS technology. The de-

vice integrates a voltage regulator, Hall sensor with

dynamic offset cancellation system, Schmitt trigger

and an open-drain output driver, all in a single pack-

age.

It incorporates advanced chopper stabilization tech-

niques to provide accurate and stable magnetic switch

points. There are many applications for this HED –

Hall Electronic Device - in addition to those listed

above. The design, specifications and performance

have been optimized for commutation applications in

5V and 12V brushless DC motors.

Thanks to its wide operating voltage range and ex-

tended choice of temperature range, it is quite suitable

for use in automotive, industrial and consumer appli-

cations.

The device is delivered in a Small Outline Transistor

(SOT) for surface mount process or in a Plastic Single

In Line (SIP 3L flat) for through- hole mount. Both

3-lead packages are RoHS compliant.
