TPS2552DBVT-1 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 greater ceramic decoupling capacitor from IN to GND as close to the IC as possible. |
| 2 | GND | power_in | Ground return for the device. In DBV (SOT-23) there is no PowerPAD; GND is the sole ground reference. |
| 3 | EN | input | Active-low enable input for the TPS2552/TPS2552-1. Logic low turns on the power switch; VIL ≤ 0.66 V, VIH ≥ 1.1 V. Input current is ±0.5 µA typ at 0 V or 6.5 V. |
| 4 | FAULT | output | Active-low open-drain fault output. Asserts low during overcurrent, overtemperature, or reverse-voltage conditions; requires an external pull-up (typ 100 kΩ). Continuous sink current 0 to 10 mA (25 mA abs max); VOL = 180 mV at 1 mA. |
| 5 | ILIM | passive | Current-limit programming pin. Connect an external 1% resistor from ILIM to GND to set the current-limit threshold; recommended range 15 kΩ ≤ RILIM ≤ 232 kΩ, giving IOS ≈ 75 mA to 1700 mA. Source current is limited to 1 mA max. |
| 6 | OUT | power_out | Power-switch output. Drain of the internal high-side PMOS (85 mΩ typ in DBV). Delivers up to 1.5 A continuous; recommend at least 120 µF bulk capacitance on downstream USB ports per USB spec. |
