MT8311 Datasheet | MagnTek

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 pensation 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 Ro HS pliant. 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 ￭ Ro HS pliant: 2011/65/EU 3 Product Overview of MT831X Part No. Description MT831XA MT831XAT MT831XET Flat TO-92, bulk packaging (1000pcs/bag) SOT-23, tape & reel (3000pcs/bag) SOT-23 (Thin Outline), tape & reel (3000pcs/bag) MT831XBT SOT-89B, tape & reel (1000pcs/bag) magntek.de | Magnetic Tech Makes Magic Change 4 Application ￭ Automotive, Home appliances, Industrial ￭ Speed Detection ￭ Position Detection ￭ Magnetic Encoder ￭ Solid-State Switch ￭ Proximity Switch 5.
