Hi,
We plan to use the TPL7407L device as a relay driver. The problem we have is that we only have 5V on the COM pin. In the datasheet it is written, that the part will still function with a voltage lower than 8.5V but that Rdson will be higher because of the lower gate drive voltage. Are there any figures that shows the Rdson versus voltage applied to COM pin? How is this affected over the whole temperature range?
Thanks and best regards,
Patrick
