FEATURES

DESCRIPTION

The TPS20xxC power-distribution switch family is

23

•

Single Power Switch Family

intended for applications such as USB where heavy

•

Pin for Pin with Existing TI Switch Portfolio

capacitive loads and short-circuits are likely to be

•

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

encountered. This family offers multiple devices with

fixed current-limit thresholds for applications between

•

±20% Accurate, Fixed, Constant Current Limit

0.5 A and 2 A.

•

Fast Over-Current Response

– 2 µs

The TPS20xxC family limits the output current to a

•

Deglitched Fault Reporting

safe level by operating in a constant-current mode

•

Output Discharge When Disabled

when the output load exceeds the current-limit

•

Reverse Current Blocking

threshold. This provides a predictable fault current

under all conditions. The fast overload response time

•

Built-in Softstart

eases the burden on the main 5 V supply to provide

•

Ambient Temperature Range:

–40°C to 85°C

regulated power when the output is shorted. The

power-switch rise and fall times are controlled to

APPLICATIONS

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