Output pin absolute-maximum-rating value of TPS7A6650-Q1

Other Parts Discussed in Thread: TLE4275-Q1

Dear, All

The absolute-maximum-rating value of the output pin of TPS7A6650-Q1 is 7V.
Input power source resisting pressure is a low value to other products and products of the other company as LDO beyond about 40V.
(For example, TLE4275-Q1 is 16V.)
I would like to know the reason.
For example,
- In order to reduce - chip cost?
- A protection circuit is added which does not occur [ emitting smoke ] even if an internal sense circuit breaks down?
Please teach me the above reasons.

Thanks, Masami M.

    This has been assigned to an engineer.  Please have patience over the weekend to allow it to be answered next week.

    Hi Masami-san,

    For different applications and features, chips will have differnt output voltage and absolute-maximum-rating value. For those devices whose output max voltage can survive 7V only (such as TPS7A6650-Q1), most of their target market is for CAN and uC power supply, usually 3.3V and 5V are enough.

    For TLE4275-Q1, because it has the short to battery protect feature, and in 12 battery system, the normal voltage range is about 9-16V.

    Another reason is chip cost. As you know, higher output maximum voltage will add more cost.

    Best regards,
