Ce microcontrôleur est capable de piloter directement des MOSFET de sortie PWM triphasée, avec un incrément de temps de 25 ns. Il est donc particulièrement bien adapté pour commander de petits moteurs, des ventilateurs de serveur, de refroidissement ou de ventilation, des ventilateurs de plafond, des pompes ou des jouets.
\nLe cœur du microcontrôleur peut être alimenté par la tension du pré-driver si celle-ci est de 12 V, ce qui permet l’utilisation d’une seule source pour piloter l’ensemble du dispositif. Au-delà de cette tension, une alimentation externe de 5 V doit être fournie.
\nÉquipé d’un cœur ARM Cortex-M3 pouvant tourner jusqu’à 40 MHz, d’un CAN 12 bits et d’une plateforme de contrôle vectoriel intégrée, ce circuit fournit une commande moteur à très haut rendement, à faibles vibrations et faible bruit, capable d’améliorer largement les performances du moteur.
\nCe composant intègre également un amplificateur opérationnel, essentiel pour la détection de courant avec une simple résistance shunt, et un comparateur pour la détection de surintensité. Toutes ces fonctions sont intégrées dans un petit boîtier VQFN-32 au pas de 0.5 mm et de seulement 5 x 5 mm, minimisant ainsi la surface occupée.\n<\/p>\n
