Automotive 0.5-5A adjustable ILIMIT, 2.5-6.5V, 22mΩ USB power switch, active-high

The TPS2556-Q1 and TPS2557-Q1

power-distribution switches are specialized for automotive applications which

require precision current limiting or capacity to handle heavy capacitive loads and

short circuits. These devices offer a programmable current-limit threshold between

500 mA and 5 A (typical) via an external resistor. Control of the power-switch rise

and fall times minimizes current surges during turnon or turnoff.

TPS2556-Q1 and TPS2557-Q1 devices

limit the output current to a safe level by switching into a constant-current mode

when the output load exceeds the current-limit threshold. The

FAULT logic output asserts low during overcurrent and

overtemperature conditions.

Use with the TPS2511-Q1 or TPS2513A-Q1

for a low-loss, automotive-qualified, USB charging-port solution capable of charging

all of today’s popular phones and tablets.
