Functional Diagram

Description

The US5881 is a unipolar Hall effect sensor IC fab-

ricated from mixed signal CMOS technology. It in-

corporates advanced chopper stabilization tech-

niques to provide accurate and stable magnetic

switch points. There are many applications for this

sensor in addition to those listed above. The de-

sign, specifications and performance have been

optimized for applications of solid state switches.

Regulator

The output transistor will be switched on (B_OP) in

the presence of a sufficiently strong South pole

magnetic field facing the marked side of the pack-

age. Similarly, the output will be switched off (B_RP)

in the presence of a weaker South field and remain

off with “0” field. The SOT-23 device is reversed

from the UA package. The SOT-23 output transis-

tor will be switched on (B_OP) in the presence of a

sufficiently strong North pole magnetic field sub-

jected to the marked face.

Note: This is a static-sensitive device; please observe ESD precau-

tions. Reverse V_DDprotection is not included. For reverse voltage

protection, a 100

Wresistor in series with V_DDis recommended.
