HALL-EFFECT SWITCH

FOR 2-WIRE APPLICATIONS

APPLICATIONS INFORMATION

External Components. It is strongly recommended

that an external bypass capacitor be connected (in close

proximity to the Hall sensor) between the supply and

ground of the device.

Power Derating. Due to the internal device power

dissipation, the junction temperature (TJ) will be higher

than the ambient temperature (TA). To ensure that the

absolute maximum junction temperature is not exceeded,

the following equations should be applied:

TJ = TA + (PD x RθJA)

where PD is the maximum supply power

IOUT(H) x VCC

and RθJA is the package thermal resistance. The specified

limit for IOUT(H) should be used to ensure a margin of

safety.

Magnets. The simplest form of magnet that will operate

this device is a ring magnet. Other methods of operation,

such as linear magnets, are possible.
