3250 AND 3251

PROGRAMMABLE,

CHOPPER-STABILIZED,

HALL-EFFECT SWITCHES

APPLICATIONS INFORMATION

Power Derating. Due to the internal device power

dissipation, the junction temperature (T_J) will be higher

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

absolute maximum junction temperature is not exceeded,

the following equations should be applied:

External Components. It is strongly recommended

that an external bypass capacitor be connected (less than 5

mm from the Hall sensor) between the supply and ground

of the device to reduce both external noise and noise

generated by the chopper-stabilization technique.

T_J= T_A+ (P_Dx R_θJA

where P_Dis the sum of the supply power

_CCx V_CC

)

A series resistor (R_S) in combination with the bypass

capacitor prevents external EMC pulses from affecting the

sensor. The voltage drop across this resistor subtracts

from the supply voltage and must be considered.

and the output power

I_OUTx V_OUT(SAT)

_SUPPLY≥ V_CC(min)+ (I_CCx R_S)

and R_θJAis the package thermal resistance. The specified

limits for I_CCand V_OUT(SAT)should be used to ensure a

margin of safety. Note that if an over-voltage condition

occurs, I_CCwill increase, limited only by the Zener

voltage and the external R_S, and the device will likely be

thermally stressed.

where V_SUPPLYis the minimum supply value (including

transients), V_CC(min)is the specified minimum supply

voltage, I_CCis the specified maximum supply current and

R_Sis the maximum series-resistor value (including toler-

ances). A low operating supply voltage requires a low-

value resistor, but noise and other considerations suggest a

high-value resistor. Therefore, specify the highest value

resistor that will still allow meeting the minimum operat-

ing supply voltage requirement. This will also help to

minimize package power dissipation (especially under

over-voltage conditions).

Magnets. The simplest form of magnet that will operate

these devices is a ring magnet. Other methods of opera-

tion, such as linear magnets, are possible.

If not included as part of the load, the output pullup

resistor should be chosen to limit the current through the

output transistor. Do not exceeed the absolute maximum

rated output current. Internal current limiting is only

intended to protect the device from output short circuits.
