TPL7407L: output7

Part Number: TPL7407L

Hi team,

As shown in the datasheet, if the application has an inductive load connected to OUT7, it is recommended to use an external Schottky diode to protect the OUT7 pin from negative transients larger than those listed in the Absolute Maximum Ratings table.
Why is there a special emphasis on OUT7? It's because the design of the output OUT1-6 inside the chip are different?  Does the OUT 1-6 need an external Schottky diode?
Thank you.
Regards,
Ivy

    Hi Ivy,

    There is a special emphasis on the OUT7 pin because that pin is the closest to the COM and the GND, or in other words, closest to the bias circuitry. Because of this, its capabilities to handle transient loads are reduced.

    We have an alternative product to this is which is the TPL7407LA, which corrects this aspect on the OUT7 pin, and doesn’t need an external Schottky diode. It is P2P, so you should have no issues in using it the same way as using the TPL7407A.

    Thanks,

    Dhanya
