SLVSAU6A –JUNE 2011–REVISED JULY 2011

Current-Limited, Power-Distribution Switches

Check for Samples: TPS20xxC

FEATURES

DESCRIPTION

The TPS20xxC power-distribution switch family is

intended for applications such as USB where heavy

capacitive loads and short-circuits are likely to be

encountered. This family offers multiple devices with

fixed current-limit thresholds for applications between

0.5 A and 2 A.

•

Single Power Switch Family

•

Pin for Pin with Existing TI Switch Portfolio

Rated currents of 0.5 A, 1 A, 1.5 A, 2 A

±20% Accurate, Fixed, Constant Current Limit

Fast Over-Current Response – 2 µs

Deglitched Fault Reporting

•

The TPS20xxC family limits the output current to a

safe level by operating in a constant-current mode

when the output load exceeds the current-limit

threshold. This provides a predictable fault current

under all conditions. The fast overload response time

eases the burden on the main 5 V supply to provide

regulated power when the output is shorted. The

power-switch rise and fall times are controlled to

minimize current surges during turn-on and turn-off.

Output Discharge When Disabled

Reverse Current Blocking

Built-in Softstart

Ambient Temperature Range: –40°C to 85°C
