Other Parts Discussed in Thread: TCAN1042HG
On the TI TCAN1051HG, pin 8 is a digital input which configures the transceiver for silent mode. Pulling this pin low, ensures normal operation.
Section 9.3.5 (Floating Terminals) states that “The S terminal is also pulled down to force the device into Normal mode if the terminal floats.”
I have elected to add a pull-down resistor on pin 8 for due diligence. I’m curious how to best size the pull down resistor on this pin… how much current would be flowing through it to ground? I’m likely to use a standard 22KΩ resistor or 100KΩ 0402 pull down, but wanted to ensure that didn’t present any issue. I can’t find any mention within the datasheet the current or power requirements of any pull-down to that pin.
I had a similar question on the TI TCAN1042HG; on this part pin 8 is a digital input which configures the transceiver for standby. Pulling this pin low, ensures normal operation.
