Caution on use of Hall ICs
As the Hall IC is often used to detect movement, the position of a Hall IC may be changed, and there is the risk of
a change in detection level, if exposed to shock or vibration over a long period of time. Secure the IC by applying
adhesive to the package or placing in a dedicated case.
1. On mounting of the surface mount type (MINI-3D package)
When mounted on the printed circuit board, the Hall IC may be highly stressed by the warping that may occur from
soldering. This may also cause a change in the operating flux density characteristic and a deterioration of its resistance
to moisture.
2. On using flux in soldering
Choose a flux which does not include ingredients from halogen group, such as chlorine, fluorine, etc. The
ingredients of halogen group may enter where the lead frame and package resin joint, causing corrosion and the
disconnection of the aluminum wiring on the surface of an IC chip.
3. On fixing a Hall IC with the holder
When a Hall IC is mounted on the printed circuit board with a holder and the coefficient of expansion of the holder
is large, the lead wire of the Hall IC will be stretched and it may give a stress to the Hall IC.
If the lead wire is stressed intensely due to the distortion of holder or board, the adhesives between the package and
the lead wire may be weakened and cause a minute gap resulting in the deterioration of its resistance to moisture.
Sensitivity may also be changed by this stress.
4. Power supply line/power transmission line
If a power supply line/power transmission line becomes longer, noise and/or oscillation may be found on the line.
In this case, set the capacitor of 0.1
μ
F to 10
μ
F near a Hall IC to prevent it.
If a voltage of 18 V or more is thought to be applied to the power supply line (flyback voltage from coil or the ignition
pulse, etc.), avoid it with external components (capacitor, resistor, Zener diode, diode, surge absorbing elements, etc.).
5. V
CC
and GND
Do not reverse V
CC
and GND. If the V
CC
and GND pins are reversely connected, this IC will be destroyed. If the
IC GND-pin voltage is set higher than other pin voltage, the IC configuration will become same as a forward biased
diode. Therefore, it will turn on at the diode forward voltage (approximately 0.7 V), and a large current will flow through
the IC, ending up in its destruction. (This is common to Monolithic IC.)
6. Cautions on power ON of Hall IC
When a Hall IC is turned ON, the position of the magnet or looseness may change the output of a Hall IC, and a
pulse may be generated. Therefore, care should be given whenever the output state of a Hall IC is critical when the
supply power is ON.
