Description
The US3881 is a bipolar Hall effect sensor IC
fabricated from mixed signal CMOS technology. It
incorporates advanced chopper stabilization
techniques to provide accurate and stable magnetic
switch points. There are many applications for this
sensor in addition to those listed above. The design,
specifications, and performance have been
optimized for commutation applications in 5V and
12V brushless DC motors.
The output transistor will be latched on (BOP) in the
presence of a sufficiently strong South pole
magnetic field facing the marked side of the
package. Similarly, the output will be latched off
(BRP) in the presence of a North field.
The SOT-23 device is reversed from the UA
package. The SOT-23 output transistor will be
latched on in the presence of a sufficiently strong
North pole magnetic field subjected to the marked
face.
ataNote: Static sensitive device; please observe ESD precautions.
.DReverse VDD protection is not included. For reverse voltage
protection, a 100W resistor in series with VDD is recommended.
