3 ] 13 by] 3 ] 0, . g ao AND ae pe These Hall-effect switches are highly temperature stable and stress- resistant sensors best utilized in applications that provide steep magnetic slopes and low residual levels of magnetic flux density. x Each device includes a voltage regulator, quadratic Hall voltage generator, temperature stability circuit, signal amplifier, Schmitt trigger and open-collector output on a single silicon chip. The on-board regulator permits operation with supply voltages of 4.5 to 24 volts. The switch output can sink up to 20 mA. With suitable output pull up, they can be used directly with bipolar or MOS logic circuits. The four package styles available provide a magnetically optimized package for most applications. Suffix LT is a surface-mount SOT-89 (TO-243AA) package; suffixes LL, U, and UA feature wire leads for 3 through-hole mounting.
