Kev tsis
SN65HVD251DR CAN transceiver yog qhov kev hloov pauv siab heev thiab poob rau hauv kev hloov pauv rau PCA82C250 thiab PCA82C251, muab cov yam ntxwv zoo dua thiab kev ua tau zoo dua qub. Nrog rau kev tiv thaiv tsheb npav muaj zog txog li +36 V, ua raws li ISO 11898 tus qauv, thiab kev txhawb nqa rau cov teeb liab nce mus txog 1 Mbps, nws ua kom muaj kev sib txuas lus txhim khu kev qha hauv cov cheeb tsam xav tau. Nws cov input impedance siab tso cai rau qhov yooj yim mus txog 120 nodes ntawm ib lub tsheb npav, thaum ESD tiv thaiv tshaj 14 KV HBM txhim khu kev ruaj ntseg. Lub transceiver qhov qis-tam sim no standby hom, thermal shutdown tiv thaiv, thiab glitch-free power-up thiab power-down sequences pab txhawb zog efficiency thiab system stability. Assigned DeviceNet Vendor ID #806, SN65HVD251DR yog ntau yam thiab txhim khu kev qha kev daws teeb meem rau ntau yam kev siv tsheb thiab kev lag luam.

Nqe lus piav qhia:
HVD251 yog tsim los siv rau hauv daim ntawv thov siv Controller Area Network (CAN) serial kev sib txuas lus lub cev txheej raws li ISO 11898 Standard. HVD251 muab qhov sib txawv ntawm kev xa mus rau lub npav thiab qhov sib txawv tau txais peev xwm rau CAN tus tswj ntawm qhov nrawm txog li 1 megabits ib ob (Mbps).
Tsim los rau kev ua haujlwm nyob rau hauv ib puag ncig hnyav, cov cuab yeej nta hla-xaim, overvoltage thiab poob kev tiv thaiv hauv av rau ± 36 V. Kuj tseem ceeb yog kev tiv thaiv overtemperature zoo li -7-V rau 12-V hom-hom ntau yam, thiab kam rau ua rau cov transients ntawm ± 200 V. Lub transceiver interfaces ib leeg-kawg CAN maub los nrog qhov sib txawv CAN tsheb npav pom nyob rau hauv kev lag luam, tsev automation, thiab kev siv tsheb.
Rs, tus pin 8, xaiv ib qho ntawm peb hom kev ua haujlwm sib txawv: kev kub ceev, kev tswj txoj kab nqes, lossis hom qis zog. Hom kev ua haujlwm siab ceev yog xaiv los ntawm kev sib txuas tus pin 8 rau hauv av, tso cai rau cov transmitter tso zis transistors hloov sai li sai tau yam tsis muaj kev txwv ntawm qhov nce thiab nqis nqes. Qhov nce thiab poob nqes hav tuaj yeem hloov kho los ntawm kev sib txuas ib qho resistor rau hauv av ntawm tus pin 8; txoj kab nqes yog proportional rau tus pin cov zis tam sim no. Kev tswj kev nqes hav nrog tus nqi hluav taws xob sab nraud ntawm 10 kΩ muab txog 15-V / µs slew tus nqi; 100 kΩ muab txog 2-V/µs slew tus nqi.
Yog tias qib siab logic tau siv rau Rs tus pin 8, lub cuab yeej nkag mus rau qhov qis-tam sim no standby hom uas tus neeg tsav tsheb raug kaw thiab lub receiver tseem ua haujlwm. Tus tswj hwm raws tu qauv hauv zos xa rov qab lub cuab yeej mus rau hom qub thaum nws xa mus rau lub npav.
