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 s
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.
