3 说明

除非另外注明，否则 TUSB320LA 和 TUSB320HA 器件（以下简称为 TUSB320）为德州仪器 (TI) 的第三代 Type-C 配置通道逻辑和端口控制器。TUSB320 器件使用 CC 引脚来确定端口的连接状态和电缆方向，以及进行角色检测和 Type-C 电流模式控制。TUSB320 器件可配置为下行端口 (DFP)、上行端口 (UFP) 或双角色端口 (DRP)，因此成为各种应用的理想选择。

根据 Type-C 规范，TUSB320 器件会交替配置为 DFP 或 UFP。CC 逻辑块通过监视 CC1 和 CC2 引脚上的上拉或下拉电阻，以确定何时连接了 USB 端口、电缆的方向以及检测到的角色。CC 逻辑根据检测到的角色来确定 Type-C 电流模式为默认、中等还是高。该逻辑通过实施 VBUS 检测来确定端口在 UFP 和 DRP 模式下是否连接成功。

该系列器件能够在宽电源范围内工作，并且具有较低功耗。TUSB320 提供两种使能版本：低电平有效使能，称为 TUSB320LA；高电平有效使能，称为 TUSB320HA。TUSB320 系列器件适用于工业级温度范围。

Pin Functions

PIN TYPE DESCRIPTION
NAME TUSB320LA TUSB320HA
CC1 1 1 I/O Type-C configuration channel signal 1
CC2 2 2 I/O Type-C configuration channel signal 2
PORT(1) 3 3 I Tri-level input pin to indicate port mode. The state of this pin is sampled when EN_N is asserted low in the TUSB320L device, EN is asserted high in the TUSB320H device, and VDD is active. This pin is also sampled following a I2C_SOFT_RESET.
H - DFP (Pull-up to VDD if DFP mode is desired)
NC - DRP (Leave unconnected if DRP mode is desired)
L - UFP (Pull-down or tie to GND if UFP mode is desired)
VBUS_DET(1) 4 4 I 5-V to 28-V VBUS input voltage. VBUS detection determines UFP attachment. One 900-kΩ external resistor required between system VBUS and VBUS_DET pin.
ADDR(1) 5 5 I Tri-level input pin to indicate I2C address or GPIO mode:
H — I2C is enabled and I2C 7-bit address is 0x67.
NC — GPIO mode (I2C is disabled)
L — I2C is enabled and I2C 7-bit address is 0x47.
ADDR pin should be pulled up to VDD if high configuration is desired
INT_N/OUT3(1) 6 6 O The INT_N/OUT3 is a dual-function pin. When used as the INT_N, the pin is an open drain output in I2C control mode and is an active low interrupt signal for indicating changes in I2C registers. When used as OUT3, the pin is in audio accessory detect in GPIO mode: no detection (H), audio accessory connection detected (L).
SDA/OUT1(1)(2) 7 7 I/O The SDA/OUT1 is a dual-function pin. When I2C is enabled (ADDR pin is high or low), this pin is the I2C communication data signal. When in GPIO mode (ADDR pin is NC), this pin is an open drain output for communicating Type-C current mode detect when the device is in UFP mode: Refer to Table 3 for more details.
SCL/OUT2(1)(2) 8 8 I/O The SCL/OUT2 is a dual function pin. When I2C is enabled (ADDR pin is high or low), this pin is the I2C communication clock signal. When in GPIO mode (ADDR pin is NC), this pin is an open drain output for communicating Type-C current mode detect when the device is in UFP mode: Refer to Table 3 for more details.
ID 9 9 O Open drain output; asserted low when the CC pins detect device attachment when port is a source (DFP), or dual-role (DRP) acting as source (DFP).
GND 10 10 G Ground
EN_N 11 — I Enable signal; active low. Pulled up to VDD internally to disable the TUSB320L device. If controlled externally, must be held low at least for 50 ms after VDD has reached its valid voltage level.
EN — 11 I Enable signal; active high. Pulled down to GND internally to disable the TUSB320H device. If controlled externally, must be held low at least for 50 ms after VDD has reached its valid voltage level.
VDD 12 12 P Positive supply voltage. VDD must ramp within 25 ms or less
(1) When VDD is off, the TUSB320 non-failsafe pins (VBUS_DET, ADDR, PORT, OUT[3:1] pins) could back-drive the TUSB320 device if not handled properly. When necessary to pull these pins up, it is recommended to pullup PORT, ADDR, and INT_N/OUT3 to the device VDD supply. The VBUS_DET must be pulled up to VBUS through a 900-kΩ resistor.
(2) When using the 3.3 V supply for I2C, the end user must ensure that the VDD is 3 V and above. Otherwise the I2C may back power the device.
