TUSB1106IPWRQ1 from Texas Instruments, in a TSSOP-16. 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 | Vpu(3.3) | power_out | Pullup supply voltage output (3.3 V ± 10%), supplies external 1.5-kΩ resistor on D+ (full-speed) or D- (low-speed); controlled by SOFTCON input. |
| 2 | SOFTCON | input | Software-controlled USB connection input; HIGH level applies 3.3 V to Vpu(3.3), LOW level sets high impedance. |
| 3 | OE | input | Output enable input (active LOW, CMOS level with respect to VCC(I/O)); enables transceiver to transmit data on USB bus. |
| 4 | RCV | output | Differential data receiver output (CMOS level with respect to VCC(I/O), 4-mA push-pull drive); driven LOW when SUSPND = HIGH, output state preserved during SE0 condition. |
| 5 | VP | output | Single-ended D+ receiver output (CMOS level with respect to VCC(I/O), 4-mA push-pull drive); for SE0 detection and error conditions, driven HIGH when VCC(5.0) and Vreg(3.3) not connected. |
| 6 | VM | output | Single-ended D- receiver output (CMOS level with respect to VCC(I/O), 4-mA push-pull drive); for SE0 detection and error conditions, driven HIGH when VCC(5.0) and Vreg(3.3) not connected. |
| 7 | SUSPND | input | Suspend mode input (CMOS level with respect to VCC(I/O)); HIGH level enables low-power state while USB bus inactive and drives RCV to LOW. |
| 8 | GND | power_in | Ground supply reference. |
| 9 | VCC(I/O) | power_in | Digital I/O supply voltage input (1.65 V to 3.6 V); when not connected, D+ and D- pins are placed in 3-state. |
| 10 | SPEED | input | Speed selection input (CMOS level with respect to VCC(I/O)); LOW selects 1.5 Mbit/s low-speed mode, HIGH selects 12 Mbit/s full-speed mode; controls slew rate of D+ and D- outputs. |
| 11 | D- | bidirectional | Negative USB data bus connection (analog, differential, 0 to 3.6 V); for low-speed mode connect via 1.5-kΩ resistor; transmits and receives differential data. |
| 12 | D+ | bidirectional | Positive USB data bus connection (analog, differential, 0 to 3.6 V); for full-speed mode connect via 1.5-kΩ resistor; transmits and receives differential data. |
| 13 | VPO | input | Differential mode driver data input (CMOS level with respect to VCC(I/O), Schmitt trigger, push-pull); used in differential input mode when MODE = HIGH. |
| 14 | VMO | input | Differential mode driver data input (CMOS level with respect to VCC(I/O), Schmitt trigger, push-pull); used in differential input mode when MODE = HIGH or single-ended FSE0 mode when MODE = LOW. |
| 15 | Vreg(3.3) | power_out | Regulated supply voltage (3 V to 3.6 V) output from internal regulator, or supply input in regulator bypass mode; minimum 0.1 μF decoupling capacitor required. |
| 16 | VCC(5.0) | power_in | Supply voltage input for internal regulator (4 V to 5.5 V); can be connected directly to USB VBUS or bypassed with Vreg(3.3) in regulator bypass mode. |
