Other Parts Discussed in Thread: TCA9548A
Hi team,
I find that there is update that TCA9548A-Q1 added grade 1 to the automotive feature, and deleted Temperature grade 3: -40°C to +85°C, Ta. The grade 1 could stand with -40-125s℃,but our device 's max junction temperature is still 90℃ written in datasheet. The real temperature is almost 105℃ in customer design.
So here are the questions:
1. why device max junction temperature is 90℃(recommended 85℃) with the AEC-Q100 grade 1;
2. do we have roadmap on I2C switch which can stand with -40-125℃ ? In ti.com, there is only one I2C switch device which can reach AEC-Q100.
YOURS
