A More Reliable Usb Based Gsm And Gprs Modem Desig

A More Reliable USB Based GSM and GPRS Modem Design Ilsoo Yang, expert reaping Marketing and SungGeun Yoon, Sr. Applications Engineer Introduction In the new-fangled Recently in the take-away electronics market, the wireless web attack to communicate with individually other and move a swear out (do you mean by transmitting/transferring the data/info? I meant wireless network tiller work process faster) send on quickly in doing his/her own business some(prenominal)where any succession is one of critical factors to be considered in design most of portable electronics. The GSM / GPRS wireless modems situation by VBUS rake of USB is can be a corking solution to enablemake portable devices environment ubiquitous. This modem design, however, challenges gives engineers a hard time in complementing with violence managements because GSM and GPRS transmitter require up to 2A neb on-line(prenominal) which exceeds readily the uttermost rate of flow capacity of USB power source even though most USB ports of electronic devices in the accredited market are able to supply up to 1A at 5V. For better reliableness in USB wireless modem (?

) designa more reliable design, they should take some(prenominal) design factors into consideration such(prenominal) as an input all over current protection to eliminate over cargoing the USB power source, a robust break converter to make the most of the positioned input source and the great unwashed sidetrack capacitors to supply enough power to the pulsed load define during GSM and GPRS transmission. The unite design of FPF2195, Intel liMAXâ„¢ and FAN8060 provides GSM/GPRS modem! designers with two important protections oflike an input over current protection and a max output current limit as it satisfies power requirements in pulsed load. The FPF2195 IntelliMAXTM in 1x1.5 WLCSP (Wafer take aim potato chip Scale Package) is a functional load switch with the adaptable current limit from 0.15A to 1.5A and a slightly low semiconductive resistance. The FPF2195 can be mounted on a comparatively small PWB (Printed Wiring Board) space with a great thermal...If you privation to get a full essay, ordering it on our website: OrderCustomPaper.com
