SII Semiconductor Corporation introduceert S-19680-serie highside-schakelaars voor vereenvoudigde controle gps-antenneverbindingen
CHIBA, Japan–(BUSINESS WIRE)– SII Semiconductor Corporation, dochteronderneming van Seiko Instruments Inc., introduceert de S-19680-serie highside-schakelaars met functies voor controle van stroom. De schakelaars vereenvoudigen de diagnose van verbindingen tussen gps-antennes en andere toepassingen in de auto-industrie. Deze nieuwe highside-schakelaars herkennen omstandigheden met nullast, een normaal circuit of kortsluiting. De schakelaars zijn gericht op toepassingen als LNA-fantoomvoeding voor gps-antennes, zoals een ADAS-locator, communicatiesystemen in voertuigen, e-calls, navigatiesystemen, audiosystemen voor de auto en infotainment.
Gps-antennes vereisen constant toezicht om vast te stellen of de antenne verbonden is of niet. Conventionele circuitontwerpen, die steunen op discrete componenten, zijn complex en nemen bij montage veel ruimte in. De S-19680 is een compact en gebruiksvriendelijk geïntegreerd circuit voor de diagnose van antenneverbindingen. De serie biedt ingenieurs een robuuste, accurate en kant-en-klare oplossing voor vereenvoudigde beoordelingen van antenneverbindingen. Daarbovenop komt het voordeel van ruimtebesparing.

GPS antennas require continuous monitoring and diagnosis to determine whether the antenna is connected or disconnected. Conventional circuit designs using discrete components are complex and the mounting area is large. The S-19680 is a compact and easy to use IC for antenna connection status diagnosis. The S-19680 Series provides the design engineer with a robust, accurate, and off-the-shelf solution to simplified diagnosis of antenna connection status with the added benefit of minimized board space.
The S-19680 Series receives the ON / OFF signal from the MCU and controls the power supply to the antenna amplifier accordingly, while also allowing for load current monitoring. An alert signal output is available for detection of open or short-circuit status of the load current. This function allows for connection status even in light-load applications down to load open detection current of 2.5mA. Additionally, there is a load limit circuit that is user selectable between 40mA and 100mA in 10mA increments. Load short-circuit detection is based on the user selected limit current x 0.3 and limit current x 1.0 (selectable in 0.1 step). Load open detection is selectable between 2.5mA and 30mA in 2.5mA increments. The S-19680 Series offers a wide power supply voltage range of 2.7V to 10.0V, an ultra low operation current consumption of 12 μA typical. The package is TMSOP-8. AEC-Q100 is in process and PPAP is available upon request.
