MT8311

MT831X Uni-polar, High Voltage Hall-Effect Switch IC 1 Product Description The MT831X family is produced by BCD technology with both high performance and high reliability. The Hall IC internally includes an on-chip Hall voltage generator, a voltage regulator for operation with supply voltage of 3.8V to 60V, temperature compensation circuitry, small-signal amplifier, Hall IC with dynamic offset cancellation system, Schmitt trigger and an open collector output. It also includes an clamp diode at output and reversed power supply protection enhances the robustness of Hall IC. The Hall IC designed to respond to a single poles. While the magnetic flux density(B) is larger than operating point (BOP), the output will be turned on (Low), the output is held until the magnetic flux density(B) is lower than releasing point (BRP), then turn off (High). The MT831X family provides a variety of packages to customers: SOT-23/SOT-23 (Thin Outline)/SOT-89B for surface mount and flat TO-92 for through-hole mount. All packages are RoHS compliant. 2 Feature ￭ BCD Technology ￭ Uni-polar Switch ￭ 3.8~60V Operating Vcc Range ￭ -40℃~150℃ Operating Temperature ￭ Package Option: Flat TO-92 SOT-23 SOT-23 (Thin Outline) SOT-89B ￭ Magnetic Sensitivity Option: MT8311 (BOP=140Gs, BRP=105Gs) MT8312 (BOP=255Gs, BRP=210Gs) MT8313 (BOP=85Gs, BRP=50Gs) ￭ Open-Drain Output ￭ -24V Reversed Power Supply Protection ￭ Output Limiting Current Protection ￭ RoHS Compliant: 2011/65/EU 3 Product Overview of MT831X Part...
