TPS2553DDBVR 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 voltage supply, 2.7 V to 6.5 V. Connect a 0.1 µF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 2 | GND | power_in | Ground connection. Connect externally to the PowerPAD. |
| 3 | EN | input | Enable input. For TPS2553D a logic-high level turns on the power switch (active-high). V_IH ≥ 1.1 V, V_IL ≤ 0.66 V. Absolute maximum 6.5 V. |
| 4 | FAULT | output | Active-low open-drain fault output. Asserted during overcurrent, overtemperature, or reverse-voltage conditions. Requires an external pull-up resistor; continuous sink current up to 10 mA (25 mA absolute maximum). |
| 5 | ILIM | passive | External resistor sets current-limit threshold. Recommended R_ILIM range 15 kΩ ≤ R_ILIM ≤ 232 kΩ, corresponding to a programmable current limit of about 75 mA to 1700 mA (typ). ILIM source current is 0-1 mA (absolute max). |
| 6 | OUT | power_out | Power-switch output. Connects to load through the internal 85-mΩ (typ) high-side MOSFET. Add a downstream bypass capacitor (e.g., 120 µF for USB compliance). |
| PAD | PowerPAD | passive | Exposed thermal pad, internally connected to GND. Used to heat-sink the part to the PCB traces. Must be connected externally to the GND pin. |
