USB Dual-Port Power Switch and Current Monitor

Features

Description

• Dual-Port Power Switches:

The UCS2114 is a dual USB port power switch

configuration that can provide 3.0A continuous current

(3.4A maximum) per V_BUSport 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.

- 2.9V to 5.5V source voltage range

- 3.0A continuous current per V_BUSport with

18 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

The UCS2114 is well-suited for both stand-alone and

applications having SMBus/I²C communications.

- Undervoltage and overvoltage lockout

- Back-drive, back-voltage protection

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). Per-port charge

rationing is also provided, ranging from 3.8 mAh to

246.3 Ah.

- Auto-recovery fault handling with low test

current

- BOOST# logic output to increase DC-DC

converter output under large load conditions

• SMBus 2.0/I²C Mode Features:

In Stand-Alone mode, the UCS2114 provides eight

current limits for both switches, ranging from

0.53A + 0.53A to 3A + 3A total continuous current

(see Table 1-1).

- Eight programmable current limits assignable

to each power switch

- Other SMBus addresses available upon

request

Both power switches include an independent V_BUS

discharge function and Constant Current mode limiting

for BC1.2 applications.

- Block read and block write

• Self-Contained Current Monitoring (No External

Sense Resistor Required)

The UCS2114 is available in a 3x3 mm 20-pin VQFN

package.

• Fully Programmable Per-Port Charge Rationing

and Behaviors

• Configurable Per-Port BC1.2 V_BUSDischarge
