JSM501-JSM511
High Voltage Hall Effect Switch Family
Vinbelltech Co. Ltd
Introduction
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 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 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 ° up to 150 °

Family Overview
The types within each family differ according to the magnetic flux density values for the magnetic switching points, the
temperature behavior of the magnetic switching points, the mode of switching, the number of pins and the average
current consumption. Table 1 to Table 4 list some devices classified in terms of switching behavior and sensitivity: higher
sensitivity correlates to lower switching points.

3-wire devices
The following definitions outline the device behavior for different switching points:
Latching Sensors:
3-wire:
The output turns low with the magnetic south pole on the branded side of the package and turns high with the
magnetic north pole on the branded side.
The output does not change if the magnetic field is removed. For changing the output state, the opposite magnetic
field polarity must be applied.
