TPS2552DBVR

TPS2552DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input supply voltage, 2.5 V to 6.5 V. Connect a 0.1 µF or larger ceramic bypass capacitor from IN to GND as close to the IC as possible. Feeds the internal high-side power MOSFET (85 mΩ).
2 GND power_in Device ground reference. All voltages are referenced to GND.
3 EN input Active-low enable input for the TPS2552 (bar-EN). A logic low turns on the internal power switch; a logic high disables the switch. Referenced to GND; do not leave floating.
4 FAULT output Active-low, open-drain fault indicator. Asserted low during overcurrent, overtemperature, or reverse-voltage conditions. Requires an external pull-up resistor (e.g. 100 kΩ to logic rail); continuous sink current rated up to 25 mA.
5 ILIM passive Current-limit programming input. Connect an external resistor R_ILIM from ILIM to GND to set the current-limit threshold (recommended 15 kΩ ≤ R_ILIM ≤ 232 kΩ, giving 75 mA to 1.7 A typ). Do not leave floating; source current ≤ 1 mA.
6 OUT power_out Power-switch output. Drain of the internal high-side MOSFET; delivers switched, current-limited supply to the load (e.g. downstream USB port). Bulk output capacitance (e.g. 120 µF for USB) recommended.
