SN65HVD231QDR

SN65HVD230Q, SN65HVD231Q, thiab SN65HVD232Q controller area network (CAN) transceivers yog tsim los siv nrog Texas Instruments TMS320Lx240x 3.3-V DSPs nrog CAN controllers, los yog nrog cov khoom sib npaug. Lawv tau npaj los siv rau hauv daim ntawv thov siv CAN serial kev sib txuas lus lub cev txheej txheej raws li ISO 11898 tus qauv. Txhua CAN transceiver yog tsim los muab kev sib txawv ntawm kev xa mus rau lub tsheb npav thiab qhov sib txawv tau txais peev xwm rau CAN maub los ntawm qhov nrawm txog 1 Mbps.

Tsim los rau kev ua haujlwm hauv qhov chaw tshwj xeeb-hnyav, cov cuab yeej no muaj kev tiv thaiv kev sib tsoo, kev poob hauv av thiab kev tiv thaiv overvoltage, tiv thaiv overtemperature, nrog rau ntau hom kev sib tw.

Lub transceiver cuam tshuam rau tib-kawg CAN maub los nrog qhov sib txawv CAN tsheb npav pom nyob rau hauv kev lag luam, tsev automation, thiab kev siv tsheb. Nws ua haujlwm dhau ntawm -2-V rau 7-V hom-hom ntau yam ntawm lub tsheb npav, thiab nws tuaj yeem tiv taus hom kev hloov pauv ntawm ± 25 V.

Ntawm SN65HVD230Q thiab SN65HVD231Q, RS (pin 8) muab peb hom kev ua haujlwm sib txawv: kev kub ceev, txoj kab nqes tswj, thiab qis zog hom. Cov kev ua haujlwm siab ceev yog xaiv los ntawm kev sib txuas tus pin 8 rau hauv av, tso cai rau cov khoom siv hluav taws xob tso tawm transistors hloov mus rau thiab tawm kom nrawm li sai tau yam tsis muaj kev txwv ntawm qhov nce thiab poob qis. Qhov nce thiab lub caij nplooj zeeg slopes tuaj yeem hloov kho los ntawm kev sib txuas cov resistor rau hauv av ntawm tus pin 8, vim txoj kab nqes yog proportional rau tus pin cov zis tam sim no. Qhov kev tswj txoj kab nqes no yog siv nrog cov nqi hluav taws xob sab nraud ntawm 10 kΩ, kom ua tiav qhov 15-V / µs slew tus nqi, mus txog 100 kΩ, kom ua tiav 2-V / µs slew tus nqi.

Lub Circuit Court ntawm SN65HVD230Q nkag mus rau qhov qis-tam sim no standby hom thaum lub sij hawm tus neeg tsav tsheb raug kaw thiab lub receiver tseem active yog hais tias ib tug siab logic theem yog siv rau RS (pin 8). Lub DSP maub los thim rov qab hom tam sim no qis tam sim no thaum lub xeev tseem ceeb (bus sib txawv voltage> 900 mV typical) tshwm sim ntawm lub npav.

Qhov sib txawv tshwj xeeb ntawm SN65HVD230Q thiab SN65HVD231Q yog tias ob tus neeg tsav tsheb thiab tus txais tau raug hloov mus rau hauv SN65HVD231Q thaum muaj qib siab logic siv rau RS (pin 8) thiab nyob twj ywm hauv hom kev pw tsaug zog no kom txog thaum lub voj voog rov ua haujlwm los ntawm qhov qis. logic theem ntawm RS.

Lub Vref (pin 5 ntawm SN65HVD230Q thiab SN65HVD231Q) yog muaj raws li VCC / 2 voltage siv.

SN65HVD232Q yog ib qho yooj yim CAN transceiver uas tsis muaj kev xaiv ntxiv; pins 5 thiab 8 yog NC, tsis muaj kev sib txuas.
