PROGRAMMABLE, CHOPPER-

STABILIZED, HALL-EFFECT SWITCH

The A3150JLT and A3150JUA programmable switches provide

tooth/valley recognition in large gear-tooth sensing applications. Each

sensor consists of a single element, chopper-stabilized Hall-effect IC

that can be programmed to the desired magnetic switch point, opti-

mizing sensor airgap and timing accuracy performance after final

packaging. The small package can be easily assembled and used in

conjunction with a wide variety of gear/target shapes and sizes. The

two devices differ only in package style.

PTCT

The sensing technology used for this sensor is Hall-effect based.

The sensor incorporates a single-element Hall IC that switches in

response to magnetic signals created by a ferrous target. The program-

mability of the circuit eliminates magnet and system offsets such as

those caused by tilt yet provides zero-speed detection capabilities

without the associated running jitter inherent in classical digital solu-

tions.

A proprietary dynamic offset cancelation technique, with an

internal high-frequency clock, reduces the residual offset voltage,

which is normally caused by device overmolding, temperature

dependancies, and thermal stress. This technique produces devices that

have an extremely stable quiescent output voltage, are immune to

mechanical stress, and have precise recoverability after temperature

cycling. Many problems normally associated with low-level analog

signals are minimized by having the Hall element and amplifier in a

single chip. Output precision is obtained by internal gain adjustments

during the manufacturing process and operate-point programming in the

user’s application.

PRELIMINARY INFORMATION

(subject to change without notice)

April 12, 1999

ABSOLUTE MAXIMUM RATINGS

This sensor system is ideal for use in gathering speed, position, and

timing information using gear-tooth-based configurations. The

A3150JLT/JUA are particularly suited to those applications that require

accurate duty cycle control or accurate edge detection. The lower

vibration sensitivity also makes these devices extremely useful for

transmission speed sensing.
