SN65HVD101: Reverse polarity protection

Part Number: SN65HVD101

Dear Sir/Madam,

1. I would like to check how the reverse polarity protection in SN65HVD101 work? if exceed the absolute maximum rating of the reverse polarity, will the IC mal-function?

2. Does this IC follow any ISO International standard/IEC ?

3. Will Ti provide any device stack library for end user to build on it or does TI has work with any third party for the device stack library that you can share? My end cust is working on IOlink for safety device.

Best Regards,
kpk

  • Hello kpk,

    1. The reverse polarity protection circuitry protects the device against accidental reverse polarity connections to the L+, CQ and L- pins. The maximum voltage between any of the pins may not exceed 40-V DC at any time. If the maximum value is exceeded the device can be permanently damaged.

    2. The SN65HVD101 was designed to meet the IO Link specification:

    IEC 61000-4-5 (IEC Surge) is mentioned in the data sheet for the SN65HVD101 with recommendations on how to protect against it.

    3. There are many TI designs on the TI website in which the physical layer and IO link protocol are implemented. You can find them here:

    I know we have licensed the IO stack for a few of these reference designs but I am not sure what the rules are for sharing this collateral. Please let me know what other questions you have?
