Each device includes a voltage regulator, quadratic Hall voltage generator, temperature compensation circuit, signal amplifier, Schmitt trigger, and an open-collector output on a single silicon chip. The on-board regulator permits operation with supply voltages of 4.5 volts to 18 volts. The switch output can sink 10 mA. With suitable output pull up, they can be used directly with bipolar or MOS logic circuits. The three package styles available provide a magnetically optimized package for most applications. Suffix ‘LT’ is a surface-mount SOT-89/ TO-243AA package; suffixes ‘U’ and ‘UA’ feature wire leads for through-hole mounting. Dwg. PH-003A Pinning is shown viewed from branded side.
