The Hall IC internally includes an on-chip Hall voltage generator, a voltage regulator for operation with supply voltages of 4.2 to 30V, Gnd and Output reverse protection diode, temperature compensation circuitry, small-signal amplifier, Schmitt trigger and an output driver with a pull-up resistor; all in a single package. It is designed to respond to alternating North and South poles. While the magnetic flux density(B) is larger than operate point (Bop), the output will be turned on (Low), the output is held until the magnetic flux density(B) is lower than release point (Brp), then be turned off (High). Thanks to its wide operating voltage range 4.2 to 30V and extended temperature range from -40 ℃to +150℃, it is quite suitable for use in automotive, industrial and consumer applications. The device is delivered in variety of packages to customers: SOT-23, and TO-92S flat for through-hole mount. Both 3-lead packages are RoHS compliant. Page 1/11 PDF
