Microchip Technology UCS2114
The UCS2114 is a dual USB port power switch configuration that can provide 3.0A continuous current (3.4A maximum) per VBUS port with precision overcurrent limiting (OCL), port power switch enables, auto-recovery fault handling, undervoltage and overvoltage lockout, back-drive and back-voltage protection, and thermal protection. The UCS2114 is well-suited for both stand-alone and applications having SMBus/I2C communications. For applications with SMBus, the UCS2114 provides per-port current monitoring and eight programmable current limits per switch, ranging from 0.53A to 3.0A continuous current (3.4A maximum).
