SLVSB28 –DECEMBER 2011

Dual Channel Precision Adjustable Current-Limited Power Switches

Check for Samples: TPS2560A, TPS2561A

FEATURES

APPLICATIONS

•

Two separate current limiting channels

Meets USB Current-Limiting Requirements

Adjustable Current Limit, 250 mA–2.8 A (typ)

•

USB Ports/Hubs

Digital TV

Set-Top Boxes

VOIP Phones

Accurate 2.1A Min / 2.5A Max Setting

(Including Resistor)

DESCRIPTION

•

Fast Overcurrent Response - 3.5-μs (typ)

Two 44-mΩ High-Side MOSFETs

Operating Range: 2.5 V to 6.5 V

2-μA Maximum Standby Supply Current

Built-in Soft-Start

The TPS2560A and TPS2561A are dual-channel

power-distribution switches intended for applications

where precision current limiting is required or heavy

capacitive loads and short circuits are encountered.

These devices offer a programmable current-limit

threshold between 250 mA and 2.8 A (typ) per

channel via an external resistor. The power-switch

rise and fall times are controlled to minimize current

surges during turn on/off.

15 kV / 8 kV System-Level ESD Capable

UL Listed – File No. E169910

CB & Nemko Certified

Each channel of the TPS2560A/61A devices limits

the output current to a safe level by switching into a

constant-current mode when the output load exceeds

the current-limit threshold. The FAULTx logic output

for each channel independently asserts low during

overcurrent and over temperature conditions.
