1A Protected High-Side Load Switch in Compact TSC75

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.

How to Miniature reed detect switch from C&K with electrical life to 1,000,000 cycles?

A miniature surface mount detect Reed switch, designed for long life and ease of use, was launched by C & K Components. The RS detect switch is a miniature reed detect an electrical cycles.

"The transitional RS has a magnetic sensor with an Omni Polar Magnetic reed, which works with a pool of a magnet," said David Webber, director of product management for C & K Components. "Thanks to the versatility and size of the miniature device, the switch is implemented in a wide range of applications for detection, and is especially ideal for those where space is scarce."

The magnetic reed switch 5 mm with a footprint of 6.5mm x 2.3mm and is the only 2.3mm off the board. The switch can detect the top or side served to increase flexibility.

The RS detect Reed switch is specified for a range of applications, including sensors, factory automation equipment, detection limit, security systems, and a fan motor controllers, and that the mere discovery applications such as pregnant locks.

The RoHS compliant detect switches are available with or Gullwing J-lead terminations, and can be delivered on the pick-and-place compatible tape and reel packaging, says the company.
