Iimpawu eziphambili zeTPS22976

Isitshixo esidityanisiweyo somthwalo ombini

Uluhlu lwamandla ombane: 0.6 V ukuya kwiV_I-BIAS

V_I-BIASUluhlu lombane: 2.5 V ukuya ku-5.7 V

Ukuchasa

R_ON= 14 mΩ (eqhelekileyo) e-V_IN= 0,6 V ukuya ku-5 V, V_I-BIAS= 5 V

R_ON= 18 mΩ (eqhelekileyo) e-V_IN= 0,6 V ukuya ku-2.5 V, V_I-BIAS= 2.5 V

I-6-Ukutshintsha okuphezulu okuqhubekayo ngoku kwitshaneli nganye

I-Quiscent yangoku ye-TPS22976, TPS22976N

37 µA (eqhelekileyo, omabini amajelo) e-V_IN= V_I-BIAS= 5 V

35 µA (eqhelekileyo, itshaneli enye) e-V_IN= V_I-BIAS= 5 V

I-Quiscent yangoku ye-TPS22976A

85 µA (eqhelekileyo, omabini amajelo) e-V_IN= V_I-BIAS= 5 V

83 µA (eqhelekileyo, itshaneli enye) e-V_IN= V_I-BIAS= 5 V

Igalelo lokulawula umda wenza ukuba kusetyenziswe i-1.2-, 1.8-, 2.5-, kunye ne-3.3-V logic

Inkcazelo ye-TPS22976

Usapho lwemveliso ye-TPS22976 lunezixhobo ezintathu: TPS22976, TPS22976A kunye ne-TPS22976N.Isixhobo ngasinye sisitshixo somthwalo wemijelo emibini ene-turnon elawulwayo.Isixhobo siqulethe ii-MOSFET ezimbini ze-N-channel ezinokusebenza ngaphaya koluhlu lwe-voltage ye-input ye-0.6 V ukuya kwi-5.7 V, kwaye inokuxhasa ubuninzi obuqhubekayo obukhoyo be-6 A ngetshaneli nganye.Umtshintshi ngamnye ulawulwa ngokuzimeleyo ngegalelo lokuvula kunye nokuvala (ON1 kunye ne-ON2), enokuthi idibanise ngokuthe ngqo kunye neempawu zokulawula umbane ophantsi.I-TPS22976 iyakwazi ukuvala i-thermal xa ubushushu be-junction bungaphezu komgubasi, ukucima ukucima.Ukutshintsha kuvula kwakhona xa ubushushu besiphambuka buzinza kuluhlu olukhuselekileyo.I-TPS22976 ikwabonelela ngokhetho oludityanisiweyo oludityanisiweyo lwe-230-Ω kwi-chip-resistor yomthwalo wokukhutshwa ngokukhawuleza xa iswitshi icinyiwe.

I-TPS22976 ifumaneka kwindawo encinci, yokugcina indawo ye-3-mm × 2-mm 14-SON iphakheji (DPU) kunye ne-thermal pad edibeneyo evumela ukuchithwa kwamandla aphezulu.Isixhobo siphawulwe ukuba sisebenze kuluhlu lobushushu bomoya osimahla obuphakathi kwe -40°C ukuya kwi-105°C.
