The Hall IC internally includes a voltage regulator for operation with supply voltage of 2.8 to 24V, a dynamic offset cancellation system, a Schmitt trigger and an open-drain output driver, all in a single package. As to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in automotive, industrial and consumer applications. It also includes an anti-reverse bias block to prevent from reverse bias condition. MT3303-EN series provide a variety of packages to customers: SOT-23 for surface mount and flat TO-92 for through-hole mount. All packages are RoHS compliant. www.magntek.com.cn Rev.3 07/2019 1 / 9 MT3303-EN Series High Voltage Omni-polar Hall-Effect Sensors VS Reference Dynamic offset cancelation Regulator Over Current Protect OUT COMP Output Driver ESD ITA ESD Hall Plate GND Functional Block Diagram Function Description Definition of Magnetic Parameters BOP: Operating Point, Magnetic flux density applied on the branded side of the package which turns the output driver ON (VOUT=Low) BRP: Release Point, Magnetic flux density applied on the branded side of the package which turns the output driver OFF (VOUT=High) BHYST: Hysteresis Window,| BOP-BRP| Definition of Switching Function VOUT (V) North Pole BOP B RP VOUT(V) 0 0 Switching Behavior www.magntek.com.cn Rev.3 07/2019 2 / 9 B RP BOP South Pole MT3303-EN Series High Voltage Omni-polar Hall-Effect Sensors OR OR S N S S N N S N O O R R OUT=High OUT=Low Switching point of AT OUT=High OUT=Low Switching point of A Note: Direction of magnetic flux, Close to the chip, Far away to the chip Pin Description MT3303A-EN MT3303AT-EN Name Number VS 1 GND OUT Description Name Number Power VS 1 Power 2 Ground GND 3 Ground 3 Open-drain Output OUT 2 Open-drain Output www.magntek.com.cn Rev.3 07/2019 3 / 9 Description MT3303-EN Series High Voltage Omni-polar Hall-Effect Sensors Electrical and Magnetic Characteristics Absolute Maximum Ratings Absolute maximum ratings are limiting values to be applied individually, and beyond which the serviceability of the circuit may be impaired.
