♠ Mokhanni oa li-valve tsa likoloi tse 4
L9305 ke mokhanni oa monolithic solenoid IC e ka lokisoang, e etselitsoeng ho laola li-solenoid tse melang bakeng sa phetiso ea othomathiki, taolo ea botsitso ba elektroniki, le lits'ebetso tse sebetsang tsa ho emisa.Likanale tse 'nè li ka hlophisoa e le bakhanni ba mahlakoreng a tlaase kapa a phahameng ka motsoako ofe kapa ofe.Sesebelisoa se kenyelletsa transistor ea matla, transistor ea recirculation le sensor ea hona joale bakeng sa transistor ea matla le ea recirculation.Meaho ena e tiisa hore tekanyo ea hona joale ha e sebetse bakeng sa mocha ka mong.
Hona joale e laoloang e ka khoneha ka har'a 0-1.5 A (mefuta e tloaelehileng), e nang le qeto ea 0.25 mA, kapa 0-2 A (e atolositsoeng), e nang le qeto ea 0.33 mA.Mosebelisi a ka beha maemo a holimo a feto-fetohang a dither holim'a sebaka se behiloeng sa hajoale.
Khokahano ea 32-bit CRC e sirelelitsoeng ea SPI e sebelisetsoa ho hlophisa le ho laola likanale tsohle le ho fana ka maikutlo a boemo ba mesebetsi eohle ea tlhahlobo.Kenyelletso e sebetsang e tlase ea reset, RESN, e sebelisoa ho tima liteishene tsohle le ho seta lirejistara tsa kahare ho boleng ba tsona ba kamehla.Tsela e sireletsehileng ea ho nolofalletsa e fanoa ka EN_DR pin le Fail Safe Pre-driver e kopantsoeng.Tsela ea ho tima e sa hlokeng letho e tiisa hore liphoso tse tebileng tsa ka hare li tima mokhanni oa pele o sireletsehileng.Pini e sebetsang e phahameng e sebetsang, EN_DR, e sebelisoa ho nolofalletsa kapa ho tima likanale tsohle.Ha EN_DR pin e le tlase, likanale kaofela lia tima.Ho fanoe ka pin ea fault output 'me e ka sebelisoa ho hlahisa tšitiso ea kantle ho microcontroller neng kapa neng ha phoso e fumanoa.Mosebelisi a ka etsa 'mapa liphoso tse itseng ho phini ea FAULTn ho latela litlhoko tsa bona tse ikhethileng tsa sistimi.
• AEC-Q100 e tšoanelehang
