Title
(EN) ISOLATED DATA TRANSFER SYSTEM
(FR) SYSTÈME DE TRANSFERT DE DONNÉES ISOLÉ
Abstract
(EN)
Methods and apparatus for providing data transfer with a drive coil to transmit information, a receive coil magnetically coupled to the drive coil, and a first magnetoresistive sensor proximate the receive coil to detect information from the receive coil. In embodiments, the drive and receive coils are separated by an isolation material. In embodiments, a signal isolator IC packages includes transmit and receive coils and a magnetic field sensing element coupled to the receive coil.

L'invention concerne des procédés et un appareil pour fournir un transfert de données à l'aide d'une bobine d'entraînement pour transmettre des informations, d'une bobine de réception couplée magnétiquement à la bobine d'entraînement, et d'un premier capteur magnétorésistif à proximité de la bobine de réception pour détecter les informations provenant de la bobine de réception. Selon des modes de réalisation, les bobines d'entraînement et de réception sont séparées par un matériau isolant. Selon des modes de réalisation, un circuit intégré d'isolateur de signal comprend des bobines d'émission et de réception et un élément de détection de champ magnétique couplé à la bobine de réception.
