Muhimmiya Pull-up Resistor ne?

Pull-up resistor yana amfani a cikin ci gaban da suka yi a cikin elektronika don in kula da hukuma na siffar alama. Yana amfani a cikin transistors da switches don in kula da tsari na voltage bayan ground da Vcc zai kasance da takara lokacin da switch ya fito (kamar pull-down resistor).

Babu wani abu mai kawo shi, shi ne wani babban resistor da aka fada a cikin supply voltage da input pin.

Wannan zai iya bincike, saboda haka za a nuna misal.

Cikin ci gaban da suka yi, akwai kawai hukumar daɗi (1) ko (0).

Idan ka duba cikin ci gaban da suka yi ta 5V. Idan voltage da ke cikin input pin ita daga 2 zuwa 5 V, hukumomi ya fiye. Kuma idan voltage da ke cikin input pin ita daga 0.8 zuwa 0 V, hukumomi ya tace.

Amma, saboda wani abu, idan voltage da ke cikin input pin ita daga 0.9 zuwa 1.9 V, cikin ci gaban da suka yi zai iya bincike don hukumomi ya fiye ko ya tace.

Don in kula da wannan halin, an amfani pull-up da pull-down resistors.

An Pull-up Resistor Yadda Yake Aiki?

Resistor an fada a cikin supply voltage da input pin. Diagram cikin ci gaban da suka yi na wannan hali ana nufin a cikin hoton da aka bayar.

Voltage na input pin yana kasance da input voltage lokacin da mechanical switch ya fito. Kuma input voltage yana zama da yake ciki a ground lokacin da mechanical switch ya kunshi.

An fada pull-up resistor da switch don in kula da tsari na voltage. Switch yana kontrola hukumomin cikin ci gaban da suka yi.

Saboda mechanical switch, an amfani power electronics switch a cikin ci gaban da suka yi.

An amfani pull-up resistor don in kula da short circuits saboda pin ba zan iya fada da ground ko supply. Idan pull-up resistor ba a fada, zai iya kasance da short-circuit ko lalace masu cikin ci gaban da suka yi.

Pull-up vs. Pull-Down Resistor

Yadda pull-down da pull-up resistors suna aiki tana nufin a cikin tabbata da aka bayar.

\[ R_{pull-up} = \frac{V_{supply} - V_{H(min)}}{I_{sink}} \]

\[ R_{pull-down} = \frac{V_{L(max)} - 0}{I_{source}} \]

An Pull Up Resistor Yadda Ka Daidaita

Ohm’s law yana daidaita pull-up resistor. Formula na pull-up resistor tana n
