JSM501-JSM511 High Voltage Hall Effect Switch Family Vinbelltech Co. Ltd Introduction to r JSM50X family consists of different Hall switches produced in BCDMOS technology. All Hall sensors include a temperature-compensated Hall plate with active offset compensation, a comparator, and an output driver. The family consists of 3-wire devices, the corresponding output driver being an opendrain output transistor and a current source respectively. The comparator compares the actual magnetic flux with the fixed reference values (switching points). Accordingly the output transistor is switched on or off in 3-wire version. The active offset compensation leads to constant magnetic characteristics over supply voltage and temperature range. In addition, the magnetic parameters are robust against mechanical stress effects. The sensors are designed for industrial and automotive applications and operate with supply voltages from 2.7 V to 30V in ambient temperature range from -40 °C up to 150 °C. uc The family JSM50X is available in SOT-23 and the leaded version TO92S packages.

Functional Description JS MI JSM50X Hall effect sensor switches are available with different magnetic switching levels and output polarity. JSM50X sensors are monolithic integrated circuits which switch in response to magnetic fields. If a magnetic field with flux lines perpendicular to the sensitive area is applied to the sensor, the biased Hall plate forces a Hall voltage proportional to this field. The Hall voltage is compared with the actual threshold level in the comparator. If the magnetic field exceeds the threshold levels, the output stage (open drain output for 3-wire devices or current source for 2-wire devices) is switched to the appropriate state. The built-in hysteresis eliminates oscillation and provides switching behavior of output without bouncing. Magnetic offset caused by mechanical stress is compensated by using the chopping offset compensation technique. A serial resistor or diode on the supply line is not required thanks to the built-in reverse voltage protection. www.jsmsemi.com 第６页，共１５页 JSM501-JSM511 High Voltage Hall Effect Switch Family Vinbelltech Co.output Ltd is forced to a safe, high-impedance state (tri-state), in any of the following fault conditions: The open drain overtemperature, and undervoltage.
