TUSB1106IPWRQ1

Texas Instruments · USB Converters · TSSOP-16

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.
