The TPS2554DRCR from Texas Instruments is an adjustable current-limited power distribution switch. It is designed for applications where precise current limiting is essential or where heavy capacitive loads and short circuits are encountered. This device offers a programmable current-limit threshold between 500 mA and 2.5 A via an external resistor, with two independently settable current-limit thresholds.
The TPS2554DRCR operates with an input voltage range of 4.5V to 5.5V and features a low typical on-resistance of 73mOhm. It includes fault protection for current limiting, over temperature, and undervoltage lockout (UVLO). The switch type is general purpose, with an N-channel output configuration operating on the high side. The interface is a simple On/Off control.
This power distribution switch is housed in a 10-VSON (3x3) package and is surface-mount compatible. It meets USB current-limiting requirements and provides a fast overcurrent response of 1.5 μs typical. The device also features a low standby supply current of 3.8 μA maximum and automatic output discharge when disabled.
