Frequently Asked Questions
What is the current limiting range of the TPS2552DBVT?
The TPS2552DBVT supports an adjustable current limit ranging from approximately 75mA to 1.8A, set by an external resistor connected to the ILIM pin. This allows system designers to precisely protect downstream loads without relying on fuses or resettable polyfuses.
What is the input voltage range of the TPS2552DBVT?
The TPS2552DBVT operates over an input voltage range of 2.5V to 6.5V maximum, making it compatible with USB 5V rails, single-cell Li-ion batteries (3.0V–4.2V), and 3.3V logic power supplies. This broad range makes it versatile for portable and USB-powered designs.
What package does the TPS2552DBVT use and how many pins does it have?
The TPS2552DBVT is housed in a 6-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G6). This tiny package is well suited for space-constrained portable and wearable designs where every square millimeter of PCB area matters.
What happens when the TPS2552DBVT detects an overcurrent condition?
When output current exceeds the set limit, the TPS2552DBVT enters a constant-current limiting mode, clamping the output to the programmed current level. An open-drain fault flag output asserts active-low to signal the fault condition to the host microcontroller, enabling intelligent system-level power management responses.
Is the TPS2552DBVT suitable for USB power delivery applications?
Yes, the TPS2552DBVT is well suited for USB bus-powered applications operating at 5V (within its 2.5V to 6.5V input range). The adjustable current limit can be set to 500mA or 900mA to comply with USB 2.0 and USB 3.0 charging specifications, protecting both the host port and the connected device.
