 Gr\u00e2ce \u00e0 leur commutation progressive, ils garantissent un faible niveau d’EMI et de bruit acoustique, ce qui les rend parfaits pour les applications d\u2019habitacle automobile comme les ventilateurs de refroidissement de chargeurs sans fil, de calculateurs, ou de syst\u00e8mes audio ou multim\u00e9dia. Configur\u00e9s en driver \u00ab\u00a0full bridge\u00a0\u00bb capable de piloter des courants moteur jusqu’\u00e0 300 mA et de fonctionner sous une tension d’alimentation de 1,8V \u00e0 5V, ces dispositifs int\u00e8grent un capteur \u00e0 effet Hall ultra-sensible. Des protections int\u00e9gr\u00e9es contre l\u2019inversion de polarit\u00e9 et le blocage de rotor, ainsi qu\u2019une protection thermique, assurent la robustesse de ces drivers, m\u00eame avec les applications les plus s\u00e9v\u00e8res.<\/p>\n

Ces cirtcuits sont conditionn\u00e9s dans un minuscule bo\u00eetier UTDFN6 de seulement 0,4 mm d\u2019\u00e9paisseur, n’occupant que 3 mm2<\/sup> sur le circuit imprim\u00e9, ce qui en fait de parfaits candidats pour l’int\u00e9gration dans des ventilateurs ultra-minces. L’US168 int\u00e8gre un signal de sortie compte-tours (FG), et l’US169 dispose d\u2019un signal de sortie alarme (RD).<\/p>\n
