The ‘Bell Swoosh’ will determine the pattern of the semiconductor industry recovery, according to Dave Bell, CEO of Intersil in a talk to the Globalpress Summit Conference in Santa Cruz today.

Linear Technology has introduced a front-end over-voltage and over-current protection chip that stops errant power supplies blowing up portable electronics. "Overvoltage events can occur due to power adapter failure or faults...

Protection from electrostaic discharge in hot-swappable systems can be implemented both on and off the board, writes Richard Wilson To protect hot-swappable boards from electrostatic discharge, Rittal has come up with an electrostatic discharge (ESD) facility which is designed to remove all built-up charge from the front panel of the plug-in board and so brings the panel to protective earth potential. ...
