UCS2112 - USB Dual-Port Power Switch and Current Monitor

Datasheet Summary

Description

The UCS2112 is a dual USB port power switch configuration which 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 protection and back-vo

Features

  • Dual-Port Power Switches: - 2.9V to 5.5V source voltage range - 3.0A continuous current per VBUS port with 40 m On resistance per switch - Independent port power switch enable pins - DUAL fault ALERT# active drain output pins - Constant Current or Trip mode current limiting behaviors - Undervoltage and overvoltage lockout - Back-drive, back-voltage protection - Auto-recovery fault handling with low test current - BOOST# logic output to increase DC-DC converter output under large load.
