Description
The SS421 Series Adjustable Hall-effect Under-speed Detectors are designed to
monitor fan or motor performance. This temperature-compensated, Hall-effect IC
contains a timing circuit and logic, that senses magnetic input frequency. The
internal circuitry contains a timer so that one or two pulses at a slower repetition
rate than the set point do not produce an unwanted output.
A small amount of hysteresis has been built into the output so that operation right
at the set point does not result in a chattering output. The user simply provides an
external resistor and capacitor combination to select the RPM trip point that will fit
the particular application.
Features
flexibility
consistent operation with low-cost
magnets
counting using ring magnets
simplifies and reduces the cost of PC
board design
external resistor and capacitor
Wide temperature ranges for design
Temperature compensated for
Bipolar operation for easy RPM
Built-in timing circuit greatly
Speed trip point adjustable with
SS421H Adjustable Hall-effect
Underspeed Detector (Active - High);
SIP-4 radial lead IC package
Potential Applications
start-up
Under-speed detection for fans
Conveyors
Motor control
Power-up fault failure filter in motor
