ULN 2003

Na nke a post, anyị ga-enyocha pinout, ọrụ, na njikọ schematics nke ULN 2003, yana ihe atụ ngwa, na mgbakwunye na ọrụ ya dị ka onye na-ahụ maka relay. N'ụzọ dị otú a anyị na-agbakwụnye akụkụ ọhụrụ ọzọ na ndepụta ogologo anyị nke ngwaọrụ ewepụtara.

Kedu ihe ị chọrọ ULN2003 maka?

ULN2003 MODULE

Otu njikwa otu nwere nhazi nke njikwa ọrụ nke na-achịkwa ọkwa voltaji na ntinye na ntinye ha, yana oge, PWM, nkwụsịtụ, na usoro mgbanwe. Ọrụ nchịkwa ndị a na-enye anyị ohere ịmepụta ọtụtụ ọrụ na-enweghị ihe mgbochi na sekit njikwa dum. Iji mepụta ọtụtụ ọrụ, a na-eji njikwa na nhazi dị mfe. Nsogbu bụ ibelata sekit nke nnukwu voltaji ozugbo kpọmkwem ugbu a.

na dc moto A na-eji voltaji dị elu mee ihe n'ọtụtụ ebe n'ihi ike ike ya. Nsogbu bụ ka esi ejikwa na ibelata sekit nke nnukwu voltaji DC akụrụngwa. Iji chịkwaa ibu DC voltaji dị elu ruo 50 V na 500 mA, a na-eji sekit mgbagha nwere transistor Darlington (NPN). Sekit a nwere ike ijikwa otu ibu. Iji dozie nsogbu a, ewebata ULN2003 IC.

Kedu ihe bụ ULN2003?

PINOUT na mpempe data

Nke a IC nwere nnukwu nhọrọ nke ngwa. Nwere ike ijikwa ihe ruru ibu asaa n'otu oge na-eji transistors Darlington asaa. ULN2003 dị n'ụdị ngwugwu dị iche iche dịka SOP, PDIP, TSSOP, na SOIC. ULN2003 nwere ntụtụ mmepụta asaa enwere ike iji na-adabereghị na ntinye ntinye iji mepụta sekit transistor. IC dakọtara na sekit ọ bụla na-enweghị nnukwu ohere.

Ebe ọ bụ na voltaji mmepụta na-adabere na voltaji ntinye, enwere ike iji ya na sekit ọ bụla dị ka microcontroller ma ọ bụ microprocessor. Oke voltaji maka ibu bụ 50V, mana oke dị ugbu a bụ 500mA. Enwere ike ịgbatị oke a ma ọ bụrụ na ejiri ọtụtụ ntụtụ mmepụta. A na-echekwa ULN2003 megide ugboro ugboro ma nwee usoro nchebe ime megide nlọghachi iji chebe ngwaọrụ.

Njirimara nke ULN2003

Na usoro nke ndị kasị pụta ìhè atụmatụ nke ULN2003 bụ:

  • Ọ nwere ike ijikwa voltaji ruo 50V (enwere ụdị nke nwere ike ịnabata ruo 100V).
  • Ugbu a enwere ike ijikwa ruru 500mA maka ntinye ọ bụla.
  • Na-agụnye diode ịkụ aka dị n'ime iji chebe ngwaọrụ ahụ.
  • Ọ nwekwara ihe nchebe sistemu flyback dị n'ime yana enwere ike iji otu ntụtụ maka chaja inductive.
  • Enwere ike ijikọ ya nke ọma na microcontrollers na bọọdụ ụdị Arduino.
  • Ọ dakọtara na echiche TTL na 5v CMOS.
  • Ihe mgbawa ULN2003 nwere ike ịbịa na ngwugwu dị iche iche dị ka SOP, TSSOP, PDIP, wdg.
  • N'ozuzu, n'ahịa ọ na-abịa na ihe ndị ọzọ agbakwunyere n'elu modul iji kwado njikọ.
