TUSB320: What are the differences between the following parts: TUSB320 TUSB320LI TUSB320HI TUSB320LAI & TUSB320HAI?

Part Number: TUSB320

When doing a part comparison on the website I get the following totally useless results:

  TUSB320LI TUSB320HI TUSB320LAI TUSB320HAI TUSB320

I could spend an unknown amount of time figuring this out but I thought I would ask here first.

  • Hello,

    This table should help determine the differences.

    Vconn 1Watt Support No No No No No
    Active Cable Detection Yes Yes Yes Yes Yes
    GPIO Mode Yes Yes Yes Yes Yes
    400KHz I2C support Yes Yes Yes Yes Yes
    1.8V and 3.3V I2C levels Yes Yes Yes Yes Yes
    Current Advertise through GPIO. Yes, Default only Yes, Default only Yes, Default only Yes, Default only Yes, Default only
    Current Advertise through I2C. Yes. Default, Mid, High. Yes. Default, Mid, High. Yes. Default, Mid, High. Yes. Default, Mid, High. Yes. Default, Mid, High.
    Current Detection through GPIO Yes. Can't detect change in current advertisement unless cable removal/insertion Yes Yes Yes Yes
    Current Detection through I2C Yes, requires software workaround to detect change in current advertisement. Yes Yes Yes Yes
    UFP-only Support Yes Yes Yes Yes Yes
    DFP-only Support Yes Yes Yes Yes Yes
    DRP (alternate between UFP and DFP) Support Yes Yes Yes Yes Yes
    Audio Accessory Yes, when DFP. Yes, when DFP or UFP. Yes, when DFP or UFP. Yes, when DFP or UFP. Yes, when DFP or UFP.
    Debug Accessory Yes, when DFP. Yes, when DFP or UFP. Yes, when DFP or UFP. Yes, when DFP or UFP. Yes, when DFP or UFP.
    Try.SRC Yes, through external SW. Yes Yes Yes Yes
    Try.SNK Yes, through external SW. Yes Yes Yes Yes
    Cable Orientation through DIR pin to control external MUX No No No No No
    Cable Orientation through I2C register Yes Yes Yes Yes Yes
    Directed to Disabled State No Yes Yes Yes Yes
    Mode Change via MODE_SELECT register in connected state Requires soft reset or cable removal. Supported in either connected or unconnected state Supported in either connected or unconnected state Supported in either connected or unconnected state Supported in either connected or unconnected state
    I2C Slave Address 0x60 or 0x61 0x47 or 0x67 0x47 or 0x67 0x47 or 0x67 0x47 or 0x67
    Debug Accessory ECR No No No Yes Yes
    ID pin Failsafe No No No Yes Yes
    VBUS Detection 4V to 28V Yes Yes Yes Yes Yes
    Dead Battery Mode Yes Yes Yes Yes Yes
    DFP waits for VBUS below VBUS_DET threshold before transitioning from AttachWait.SRC to Attached.SRC No Yes Yes Yes Yes
    HBM ESD +/- 7KV +/- 5KV +/- 5KV +/- 3KV +/- 3KV

    Also the H devices have an active high EN and the L devices have an active low EN.

  • My take-away from this is: A vs. Non A = Supply current and ESD - H vs. L = Enable signal sense.

    Thanks for getting back so quickly.
