Ce composant intègre un étage de sortie DMOS qui commande soit les deux bobines d’un moteur pas à pas bipolaire, soit deux moteurs DC. Chaque pont est capable de fonctionner jusqu’à 45V et comprend un PWM interne qui contrôle un courant de sortie allant jusqu’à 750mA.<\/p>\n

Lors d’un contrôle du courant en PWM, le courant maximum en sortie est déterminé par l’utilisateur en sélectionnant une référence de tension et une résistance de captage. Deux entrées logiques sélectionnent la limite du courant de sortie à 0%, 33%, 67% ou 100% du niveau maximum. Une entrée "Phase" sur chaque pont détermine la direction du courant dans la charge.<\/p>\n

Ce circuit est conçu pour les applications bureautiques, automobiles, industrielles et pour le marché grand public. Il est proposé dans un boîtier SOIC de surface 24 broches, avec 2 paires de broches jointes. Celles-ci fournissent une dissipation thermique maximale dans un encombrement le plus réduit possible. Ce boîtier est garanti sans plomb, avec un étamage des broches 100% étain mat.<\/p>\n
