Expanding its family of the current limit of tax and the introduction of a new high of protection device has been announced by Vishay. The load switch can operate under a supply voltage range of 2.4V to 5.5V and a handful exit 1A. The SiP4613A / B is designed for switching applications, including charging the battery switching, USB peripheral ports, hot swap, and other uses of power in laptops, PDAs, laptops and other electronic devices.
A defining the par l'utilisateur limiter le niveau actuel protégé l'entrée de tension d'alimentation de la charge excessive des courants qui peuvent causer une défaillance du système. To report a fault current CL pin will be low when the device is used in a limited state. In the stop mode, SiP4613A / B reduces the supply current to less than 1μA.
In addition to the current limit, the SiP4613A / B is protected by undervoltage lockout period and thermal shutdown. The temperature protection circuit prevents thermal runaway by turning off the switch at the intersection of the chip temperature reaches 165 C and the temperature falls below 145 C.
The opportunity to selectively turn on and shut down various system functions, and can switch between sources of supply, there are two versions of the diet. The SiP4613A has a low, so that input, while SiP4613B a high input. Available in lead (Pb)-free 6-pin package PowerPak TSC75-6, the device operates within the temperature range of-40C to +85 C, says the company.
