The AP1212 two-channel USB power switch from Anachip Corp. support each USB port with at least 500mA, cuts off up to 1.1A of current, and has a typical response time of 1?s.

Aimed at replacing metal fuses and poly switch devices, the IC is also capable of recovering in 1ms after fault current condition at soft start mode, thereby eliminating the momentary voltage drop that occurs when the switch is enabled in bus-powered applications.

Additional features of the AP1212 include thermal shutdown, undervoltage lockout, and 5V or 3.3V logic-compatible enable pins.

The AP1212 is packaged into an 8-lead SOP and PDIP, and is priced at 45 cents each in 1,000-unit quantities.
