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

(see Table 1-1).

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.
