Description

The UCS2113 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-voltage protection, and thermal protection. The UCS2113 is well suited for both stand-alone and applications having SMBus/I2C communications. For applications with SMBus, the UCS2113 provides per-port current monitoring and eight programmable current limits per switch, ranging from 0.53A to 3.0A continuous current (3.4A maximum). Per-port charge rationing is also provided ranging from 3.8 mAh to 246.3 Ah. In stand-alone mode, the UCS2113 provides eight current limits for both switches, ranging from 0.53A + 0.53A to 3A + 3A total continuous current. Both power switches include an independent VBUS discharge function and constant current mode current limiting for BC1.2 applications. The UCS2113 is available in a 4x4 mm 20-pin QFN package. **Also consider the [UCS2113-C](https://ww1.microchip.com/downloads/en/DeviceDoc/UCS2113-C-Data-Sheet-DS20006466A.pdf) with an increased current limit threshold to support third party compliance testing/proprietary USB accessory standards.**
