Hello team,
Can I ask a question about UVsup test of TCAN4550-Q1?
Test condition : Vsup 12V -> 4.5V -> 6.5V
At the recovery of Vsup, does TCAN4550-Q1 necessarily require a reset pulse by using RST pin, before initializing registers through SPI?
Without toggling RST pin, the TCAN4550-Q1 doesn’t work normally for SPI interface. So, is the RST pin the righ approach?
Thanks,
Sam Lee
