Descrizione

DESCRIZIONE

Brush DC and Stepper Drivers

Allegro offre un ampio portafoglio di soluzioni Brush DC & Stepper Drivers, sicuri e robusti. Con i gate sia integrati che MOSFET, la linecard è ideale sia per applicazioni a bassa che ad alta potenza. L’aumento del contenuto digitale con algoritmi di unità incorporate semplifica l’implementazione, mentre le funzionalità avanzate di diagnostica e protezione garantiscono una soluzione sicura e affidabile.

Il nostro team offre una vasta conoscenza dei requisiti DC e stepper, consentendoci di consigliare e soddisfano le sfide più difficili.

La linecard si compone di due principali famiglie:

A4955
Progettato per il PWM (Pulse Width Modulated) dei motori DC, l’A4955 è in grado di funzionare a 50 V e fornisce gate drive per un bridge MOSFET esterno a tutti i canali N (N-channel)

A3922
L’A3922 è un driver MOSFET di potenza a canale N (N-channel) in grado di controllare MOSFET collegati in una disposizione full-bridge (H-bridge) ed è specificamente progettato per applicazioni automotivee con alti carichi induttivi di potenza, come solenoide e attuatori per motori brush DC.

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