Ibhulorho epheleleyo yeDMOS PWM Umqhubi weMoto
Idizayinelwe ulawulo lwe-pulse wide modulated (PWM) yeenjini ze-DC, i-A4950 iyakwazi ukukhupha imisinga yencopho ukuya kwi-±3.5A kunye nombane osebenzayo ukuya kwi-40 V. Iitheminali zokufakwayo zibonelelwe ukuba zisetyenziswe ukulawula isantya kunye nendlela yemoto ye-DC ene
imiqondiso yolawulo ye-PWM esetyenziswa ngaphandle. I-Internal synchronous control rectification control circuitry inikezelwa ukunciphisa ukuchithwa kwamandla ngexesha lokusebenza kwe-PWM. Ukukhuselwa kwesekethe yangaphakathi kubandakanya ukukhuselwa kwe-overcurrent, i-motor lead short ukuya emhlabeni okanye
ukubonelela, ukuvala i-thermal kunye ne-hysteresis, ukubeka iliso kwe-VBB engaphantsi kombane, kunye nokukhusela i-crossovercurrent. Ukusetyenziswa kobushushu obuphezulu be-ambient yokusebenza, isixhobo somgangatho weemoto sinikezelwa (A4950K). Isixhobo somgangatho we-K sivavanywa ngapha nangapha
iqondo lobushushu elongeziweyo kunye noluhlu lwamandla ombane ukuqinisekisa ukuthotyelwa kwezicelo zeemoto okanye zoshishino. I-A4950 ibonelelwa ngeprofayili ephantsi ye-8-pin ye-SOICN ipakethe ene-pad eveziweyo ye-thermal (i-suffix LJ) ekhokelayo (Pb) simahla, ene-100% matte tin.
i-leadframe plating
Iziphumo ezisezantsi ze-RDS(zivuliwe).
