TUSB1106RGTR

Texas Instruments · USB Converters · HVQFN-16-EP(3x3)

TUSB1106RGTR from Texas Instruments, in a HVQFN-16-EP(3x3). 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 OE input Active-LOW output enable (CMOS level with respect to VCC(I/O)) that enables the transceiver to transmit data on the USB bus.
2 RCV output Differential data receiver output (CMOS level with respect to VCC(I/O), push-pull, 4-mA drive); driven LOW when SUSPND is HIGH and stable during SE0.
3 VP output Single-ended D+ receiver output (CMOS level with respect to VCC(I/O), push-pull, 4-mA drive); driven HIGH when no supply is connected to VCC(5.0) and Vreg(3.3).
4 VM output Single-ended D- receiver output (CMOS level with respect to VCC(I/O), push-pull, 4-mA drive); driven HIGH when no supply is connected to VCC(5.0) and Vreg(3.3).
5 SUSPND input Suspend input (CMOS level with respect to VCC(I/O)); HIGH enables the low-power state while the USB bus is inactive and drives RCV LOW.
6 GND power_in Ground supply pin on the TUSB1106 RGT package.
7 VCC(I/O) power_in Digital I/O supply voltage of 1.65 to 3.6 V, independent of VCC(5.0) and Vreg(3.3) and must never exceed Vreg(3.3); D+ and D- are 3-state when it is not connected.
8 SPEED input Speed selection input (CMOS level with respect to VCC(I/O)) that sets the D+/D- slew rate: LOW is low speed (1.5 Mbit/s), HIGH is full speed (12 Mbit/s).
9 D- bidirectional Negative USB data bus connection (analog, differential); for low-speed mode connect to Vpu(3.3) via a 1.5-kOhm resistor.
10 D+ bidirectional Positive USB data bus connection (analog, differential); for full-speed mode connect to Vpu(3.3) via a 1.5-kOhm resistor.
11 VPO input Driver data input (CMOS level with respect to VCC(I/O), Schmitt trigger) for the differential input data interface.
12 VMO input Driver data input (CMOS level with respect to VCC(I/O), Schmitt trigger) for the differential input data interface.
13 Vreg(3.3) power_out Regulated 3 V to 3.6 V output during 5-V operation, needs a decoupling capacitor of at least 0.1 uF, and is the supply input for 3.3 V ±10% operation.
14 VCC(5.0) power_in Internal regulator supply input of 4 V to 5.5 V, which can connect directly to USB VBUS; connect to Vreg(3.3) for the regulator bypass option.
15 Vpu(3.3) power_out Pullup supply voltage (3.3 V ±10%) for the external 1.5-kOhm resistor on D+ or D-; high impedance when SOFTCON is LOW, connected internally to Vreg(3.3) when SOFTCON is HIGH.
16 SOFTCON input Software-controlled USB connection input; HIGH applies 3.3 V to Vpu(3.3) for the external 1.5-kOhm pullup, allowing software connect/disconnect signaling.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
