USB Charging and Charge Detection

USB Power Switch

Diodes offers a series of power switches with an integrated current limiting circuit to protect input power supply to fall out of regulation against large current.

USB power switches are designed for turning power on/off and to provide fault protection, when the output loading exceeds the current-limit threshold or a short-circuit situation is present, the devices limit the output current by switching into a constant-current mode, when switch increase the power dissipation and cause the junction temperature to rise, a thermal protection circuit turns off the switch to prevent damage, recovery from a thermal shutdown automatically once the device has cooled sufficiently.

USB Charging and Charge Detection FAQs

Is there a replacement for an obsolete part?

Not all obsolete parts will have a direct replacement. However, we recommended that you contact your regional sales office.

What are the types of jitter?

There are several types of jitter, but the main ones are: cycle-to-cycle jitter, period jitter, half period jitter, and peak-to-peak jitter. Jitter terminology can be found in AB36: Jitter Measurement Techniques at Application Brief No. 36 or Application Note No. 27.

What is the lead finish for Pericom products? What about lead-free?

All Pericom's products that are not lead-free are composed of 85% Sn and 15% Pb. For lead-free products, they are composed of 100% matte Sn. Lead-free products are marked and ordered with the letter "E" suffix at the end of the part number.

Where can I find Mean Time Before Failure (MTBF) or Failures In Time (FIT) values for Pericom products?

FIT and MTBF data can be found at Pericom's Quality webpage.

Where can I find the information on your Pb-free and "Green" packaging?

Lead (Pb)-Free and Green information can be found on individual datasheets or Pb-Free & Green Page.
