JSM541-JSM546 High Voltage Hall Effect Switch Family Vinbelltech Co. Ltd Introduction JSM54X 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 2-wire devices, the corresponding output driver being an open-drain 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 in the current source is switched on (high current consumption) or off (low current consumption) in 2-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. to r 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. The family JSM54X is available in SOT-23 and the leaded version TO92S packages.     co mi Se  CR O  SOT-23 and TO92S packages Low current consumptions of typ. 2.5 mA Operates from 2.7 V to 30 V supply voltage Overvoltage protection capability up to 40 V Highest ESD performance up to ±12 kV Current output for 2-wire applications Magnetic characteristics are robust regarding mechanical stress effects Constant switching points over a wide supply voltage and temperature range Wide operating temperature range from -40 °C to 150 °C The decrease of magnetic flux density caused by rising temperature in the sensor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics Reverse-voltage protection at Vcc pin Ideal sensor for applications in extreme automotive and industrial environments Qualified according to AEC-Q100 test standard for automotive electronics industry to provide the highest quality expectation Speed and RPM sensing Tachometer, counter pickup Flow-rate sensing Brushless dc motor commutation Motor and fan control Robotics control Proximity sensor Position sensor Seat position detection Seat belt buckles Hood/trunk/door latches Sun roof/convertible top/tailgate/liftgate actuation Brake/clutch pedals Electric power steering (EPS) Transmissions and shift selectors Wiper motor     Package JS MI                    nd Features uc Applications SOT23 www.jsmsemi.com TO92 第１页，共１２页 JSM541-JSM546 High Voltage Hall Effect Switch Family Vinbelltech Co.

JSM54X 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 to r threshold levels, the output stage (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 uc serial resistor or diode on the supply line is not required thanks to the built-in reverse voltage protection. nd The open drain output is forced to a safe, high-impedance state (tri-state), in any of the following fault conditions: overtemperature, and undervoltage. In addition, the output current is limited (short-circuit protection). co The device is able to withstand a maximum supply voltage of 28 V for unlimited time and features overvoltage capability JS MI CR O Se mi (40V load dump).
