Kev piav qhia dav dav
MAX8969 yog ib qho yooj yim 1A kauj ruam-up converter nyob rau hauv ib pob me me uas ua hauj lwm nyob rau hauv ib leeg-cell Li-ion daim ntawv thov.This IC muab kev tiv thaiv nta xws li input undervolt hnub nyoog lockout, luv luv Circuit Court, thiab overtemperature shutdown.IC hloov mus hla hom seamlessly nyob rau hauv lub teeb load tej yam kev mob los txhim kho efficiency.Raws li cov xwm txheej no, kev hloov pauv tsuas yog tshwm sim raws li qhov xav tau, txo qis kev hloov pauv thiab muab tam sim no kom muaj txiaj ntsig zoo.Rau kev ua haujlwm siab dua thaum cov khoom siv hluav taws xob nyob ze dua rau qhov tso zis hluav taws xob, muaj ob txoj haujlwm tshwj xeeb ntawm kev ua haujlwm: khiav thiab tsis siv neeg khiav.Cov qauv no tso cai rau cov neeg siv kom sib npaug quiescent tam sim no (IQ) vs. lub sij hawm teb cov lus teb mus rau hauv boost hom.Hauv ob hom, p-channel MOSFET ua raws li kev hloov pauv tam sim no xws li VOUT ua raws VIN.Txawm li cas los xij, hauv hom kev taug qab, qhov kev txhawb nqa hluav taws xob raug cuam tshuam thiab lub kaw lus tswj kev txhawb nqa nrog EN, TREN inputs (IQ = 30µA).Nyob rau hauv hom tsis siv neeg khiav (ATM), lub boost circuits yog enabled thiab cov cuab yeej cia li hloov mus rau hauv boost hom thaum VIN poob rau 95% ntawm lub hom phiaj VOUT (IQ = 60µA).Lub IC muaj nyob rau hauv ib tug me me, 1.25mm x 1.25mm , 9-pob WLP (0.4mm suab) pob.
