♠ LM7480-Q1 Ideal Diode Controller nrog Load Dump Protection
Lub LM7480x-Q1 zoo tagnrho diode maub los tsav thiab tswj sab nraud rov qab rau sab nraub qaum N-Channel MOSFETs kom ua raws li qhov zoo tshaj plaws diode rectifier nrog lub zog txoj kev ON / OFF tswj thiab tiv thaiv overvoltage. Cov tswv yim dav dav ntawm 3 V txog 65 V tso cai rau kev tiv thaiv thiab tswj ntawm 12-V thiab 24-V automotive roj teeb powered ECUs. Cov cuab yeej tuaj yeem tiv taus thiab tiv thaiv cov khoom thauj los ntawm qhov tsis zoo ntawm cov khoom siv hluav taws xob mus rau -65 V. Ib qho kev sib xyaw ua ke zoo tshaj plaws diode maub los (DGATE) tsav thawj MOSFET los hloov Schottky diode rau kev tiv thaiv kev tawm tswv yim rov qab thiab tso zis hluav taws xob. Nrog ib tug thib ob MOSFET nyob rau hauv lub hwj chim txoj kev lub cuab yeej tso cai load disconnect (ON / OFF tswj) thiab overvoltage tiv thaiv siv HGATE tswj. Cov cuab yeej muaj qhov kho tau overvoltage txiav tawm kev tiv thaiv feature. LM7480-Q1 muaj ob qhov sib txawv, LM74800-Q1 thiab LM74801-Q1. LM74800-Q1 ua haujlwm thim rov qab tam sim no thaiv siv cov kev cai tawm thiab cov qauv sib piv piv rau LM74801-Q1 uas txhawb nqa cov qauv sib piv. Nrog Common Drain configuration ntawm lub hwj chim MOSFETs, qhov nruab nrab-taw tes yuav siv tau rau OR-ing designs siv ib tug zoo tagnrho diode. Lub LM7480x-Q1 muaj qhov ntsuas qhov siab tshaj plaws ntawm 65 V. Cov loads tuaj yeem tiv thaiv los ntawm kev txuas ntxiv overvoltage transients zoo li 200-V Unsuppressed Load Dumps hauv 24-V Roj teeb tshuab los ntawm kev teeb tsa lub cuab yeej nrog MOSFETs sab nraud hauv Common Source topology
