I-Full-Bridge DMOS PWM Motor Driver
Idizayinelwe ukulawulwa kwe-pulse wide modulated (PWM) yamamotho e-DC, i-A4950 iyakwazi ukukhipha amandla aphezulu ukuya ku-±3.5A kanye nama-voltage okusebenza aye ku-40 V. Amatheminali okokufaka ahlinzekwe ukuze asetshenziswe ekulawuleni ijubane nendlela yemoto ye-DC ene
amasignali okulawula e-PWM asetshenziswe ngaphandle. Ukujikeleza kokulawula ukulungiswa kokuvumelanisa kwangaphakathi kunikezwa ukuze kwehliswe ukuchithwa kwamandla ngesikhathi sokusebenza kwe-PWM. Ukuvikelwa kwesekethe yangaphakathi kuhlanganisa ukuvikelwa kwe-overcurrent, motor lead short to ground or
ukuhlinzeka, ukuvala ukushisa okushisayo nge-hysteresis, ukuqapha okungaphansi kwe-VBB, nokuvikelwa kwe-crossovercurrent. Kuzinhlelo zokusebenza ezisezingeni eliphezulu zokusebenza kwe-ambient, idivayisi yebanga lezimoto inikezwa (A4950K). Idivayisi yezinga lika-K ihlolwe yonkana
Amazinga okushisa anwetshiwe kanye namazinga kagesi ukuze kuqinisekiswe ukuthotshelwa kwezicelo zezimoto noma zezimboni. I-A4950 ihlinzekwa ngephakheji ye-SOICN enephrofayili engu-8-pin ene-thermal pad eveziwe (isijobelelo se-LJ) esingakhokhelwa (Pb) esingenawo umthofu (Pb), esinama-matte tin angu-100%.

Okuphumayo kwe-RDS(kuvuliwe) okuphansi
• Ukuvikelwa kwe-Overcurrent (OCP)
▫ Ukuvikela okufushane kwezimoto
▫ Izimoto zihola kancane ekuvikelweni komhlaba
▫ Motor iholela iDemo ekuvikelweni ibhethri
• Imodi yokulinda Amandla Aphansi
• Umkhawulo wamanje we-PWM olungisekayo
• Ukulungisa okuhambisanayo
• I-Internal undervoltage lockout (UVLO)
• Ukuvikelwa kwe-Crossover-current
• I-A4950K iqeqeshelwe i-AEC-Q100 Ibanga loku-1
• Ibanga lokushisa lezentengiso (A4950E: -40°C kuya ku-85°C)
• Ibanga lokushisa kwezimoto (A4950K: -40°C kuya ku-125°C)
