FEATURES DESCRIPTION
The TPS2552/53 and TPS2552-1/53-1 power- 2• Up to 1.5 A Maximum Load Current
distribution switches are intended for applications • ±6% Current-Limit Accuracy at 1.7 A (typ) where precision current limiting is required or heavy
• Meets USB Current-Limiting Requirements capacitive loads and short circuits are encountered
• Backwards Compatible with TPS2550/51 and provide up to 1.5 A of continuous load current.
• Adjustable Current Limit, 75 mA–1300 mA (typ) These devices offer a programmable current-limit threshold between 75 mA and 1.7 A (typ) via an
• Constant-Current (TPS2552/53) and Latch-off external resistor. Current-limit accuracy as tight as
(TPS2552-1/53-1) Versions ±6% can be achieved at the higher current-limit
• Fast Overcurrent Response - 2-μs (typ) settings. The power-switch rise and fall times are
• 85-mΩ High-Side MOSFET (DBV Package) controlled to minimize current surges during turn on/off.
• Reverse Input-Output Voltage Protection
TPS2552/53 devices limit the output current to a safe • Operating Range: 2.5 V to 6.5 V level by using a constant-current mode when the
• Built-in Soft-Start output load exceeds the current-limit threshold.
• 15 kV ESD Protection per IEC 61000-4-2 (with TPS2552-1/53-1 devices provide circuit breaker
External Capacitance) functionality by latching off the power switch during
overcurrent or reverse-voltage situations. An internal
• UL Listed – File No. E169910 and NEMKO reverse- voltage comparator disables the power-
IEC60950-1-am1 ed2.0 switch when the output voltage is driven higher than
• See the TI Switch Portfolio the input to protect devices on the input side of the
switch. The FAULT output asserts low during
APPLICATIONS overcurrent and reverse-voltage conditions.

• Digital TV
• Set-Top Boxes
• VOIP Phones
