Liab A4988 Stepper Tsav Tsheb (nrog Heatsink, 2A)
Kev piav qhia:
· A4988 yog tus tsav tsheb microstepping tag nrog tus neeg txhais lus hauv tsev ua haujlwm kom yooj yim. Cov khoom yuav ua kom tiav, ib nrab, 1/4, 1/8 thiab 1/16 kauj ruam kev khiav lag luam me nyuam yaus ua tiav tsav tsheb mus txog 35 V thiab ± 2 A. A4988 nrog rau kev tswj hwm tam sim no, tus tswj yuav qeeb los yog tov lwj hom. Lub converter yog tus yuam sij rau txoj haujlwm yooj yim ntawm A4988. Thaum nkag mus hauv ib lub plhaub ntawm STEP nkag, lub tshuab tsav ib microstep. Tsis muaj txheej txheem cov lus sibtham, cov kab ntau qhov tswj, lossis txoj haujlwm yoog. A4988 interface yog zoo heev rau txoj microprocessor complex tsis txaus los yog muaj overburdened.
· Micro-kauj lag luam, chopping tswj nyob rau hauv lub A4988 txiav txim siab xaiv txoj kev lwj tam sim no (Qeeb los yog Mixed). Nyob rau hauv cov hom tshuaj tua kab hom, cov cuab yeej yog pib teeb tsa kom muaj cov hniav lwj hauv qhov chaw ua haujlwm dhau sijhawm, tom qab ntawd qhov qeeb qeeb nyob rau ntawm lub sijhawm poob qis. Mixed-decay tam sim no tswj tau txo cov suab nrov suab nrov, nce kauj ruam, thiab txo hwj chim noj. Internal synchronous rectification tswj circuitry lug txhim khu cov mem tes-dav tes taws los piav (PWM) zog noj thaum khiav hauj lwm. Kev tiv thaiv ntawm sab nraud xws li: thermal shutdown nrog hysteresis, undervoltage lockout (UVLO) thiab crossover kev tiv thaiv tam sim no. Tshwj xeeb zog-Tsi.
· A4988 nta Mount QFN pob (ES), qhov loj me ntawm 5 hli × 5 hli nominal siab qhov dav qhov siab ntawm 0.90 mm, thiab nrog rau lub ncoo rau cov thermal dissipation enhanced. Lub pob yog Pb (sonic-T), nrog 100% matte tin leadframe plating.
