TPS2561DRCR from Texas Instruments, in a VSON-10-EP(3x3). 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 | GND | power_in | Ground connection; connect externally to the thermal pad. |
| 2 | IN | power_in | Input voltage (2.5 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. Pins 2 and 3 are tied together internally as the shared input to both channels. |
| 3 | IN | power_in | Input voltage (2.5 V to 6.5 V). Second IN pin, shared with pin 2. |
| 4 | EN1 | input | Enable input for channel 1 (TPS2561 variant, active-high). Logic high turns on the channel-one power switch. VIH ≥ 1.1 V, VIL ≤ 0.66 V; input voltage range 0 to 6.5 V. |
| 5 | EN2 | input | Enable input for channel 2 (TPS2561 variant, active-high). Logic high turns on the channel-two power switch. VIH ≥ 1.1 V, VIL ≤ 0.66 V; input voltage range 0 to 6.5 V. |
| 6 | FAULT2 | output | Active-low open-drain fault output for channel 2, asserted during overcurrent or overtemperature condition. Requires external pull-up; max sink current 25 mA (10 mA recommended). |
| 7 | ILIM | output | External resistor to GND sets the current-limit threshold for both channels. Recommended 20 kΩ ≤ RILIM ≤ 187 kΩ, corresponding to a current-limit range of approximately 2.8 A down to 250 mA per channel. |
| 8 | OUT2 | power_out | Power-switch output for channel 2. Continuous output current 0 to 2.5 A; rDS(on) typ 44 mΩ. |
| 9 | OUT1 | power_out | Power-switch output for channel 1. Continuous output current 0 to 2.5 A; rDS(on) typ 44 mΩ. |
| 10 | FAULT1 | output | Active-low open-drain fault output for channel 1, asserted during overcurrent or overtemperature condition. Requires external pull-up; max sink current 25 mA (10 mA recommended). |
| PAD | Thermal Pad | power_in | Exposed thermal pad on package bottom, internally connected to GND. Used to heat-sink the part to the circuit-board traces; must be externally connected to the GND pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 530 faces against 74 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
