DESCRIZIONE

Brushless DC Drivers

Facile da implementare. Estremamente efficiente. La famiglia QuietMotion di Allegro offre i leader di mercato dei controller di motori elettrici Field Oriented Control (FOC) brushless DC (BLDC) che sono privi di codice cliente. I dispositivi sono progettati per fornire prestazioni a basso rumore udibile, affidabili ed efficienti, riducendo al contempo il tempo di ciclo di progettazione con semplici impostazioni dei parametri tramite GUI di facile utilizzo.

La vasta offerta di prodotti sviluppati secondo ISO 26262 aiuta i nostri clienti a soddisfare i nuovi requisiti critici per la sicurezza.

Per questa categoria due famiglie:

A89301
L’A89301 è un motor driver trifase (gate driver) brushless DC (BLDC) sensorless in grado di funzionare da 5,5 a 50 V, una delle prime soluzioni QuietMotion di Allegro. L’A89301 è ideale per ventilatori a soffitto, ventilatori a colonna, aspiratori da bagno e ventilatori e pompe per elettrodomestici di alta qualità.

A4919
A4919 è un controller trifase da utilizzare con MOSFET di potenza esterni a canale N (N-channel)
Un esclusivo regolatore della pompa di carica fornisce un gate drive completo (> 10 V) per tensioni della batteria fino a 7 V e consentirà all’A4919 di funzionare con un gate drive ridotto fino a 5,5 V. Un condensatore di bootstrap viene utilizzato per fornire la tensione di alimentazione della batteria di cui sopra richiesta per i MOSFET a canale N (N-channel).

Nella tabella riassuntiva, tutte le caratteristiche principali di ogni singolo componente.
