MT8361A

MT836X Latch, High Voltage Hall-Effect Switch IC 1 Product Description The MT836X 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, smallsignal 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 alternating north and south 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 MT836X family provides a variety of packages to customers: SOT-23/SOT-89B/SOT-23 (Thin Outline) for surface mount and flat TO-92 for through-hole mount. All packages are RoHS compliant. 2 Features 4 Applications ￭ ￭ ￭ ￭ ￭ 5.
