TMI9290A from TMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin; the datasheet gives no specific voltage or current limit for this pin. |
| 2 | FBO | bidirectional | Current sink/source feedback node: D+ steps sink 2 μA per step up to a 70 μA maximum at 12 V output, D- steps source 2 μA per step with a 14 μA minimum at 3.6 V output, and absolute maximum voltage is -0.3 to 6.5 V. |
| 3 | NC | unconnected | No connection. |
| 4 | NC | unconnected | No connection. |
| 5 | DM | bidirectional | USB D- data line with a 20 kΩ pull-down resistance (RDM) and absolute maximum voltage of -0.3 to 6.5 V. |
| 6 | DP | bidirectional | USB D+ data line with a 500 kΩ leakage resistance (RDP) and absolute maximum voltage of -0.3 to 6.5 V. |
| 7 | NC | unconnected | No connection. |
| 8 | VDD | power_in | Power supply input with a 3.2 V to 6.4 V operating range, absolute maximum -0.3 to 6.5 V, and an internal shunt clamp at 5.7 V typical; the datasheet recommends RVDD = 2.2 kΩ and CVDD = 470 nF. |
