Hello team,
My customer has questions because they would like to confirm how TPSM84624 behaves and whether it is dangerous or not.
1) DNC pin (open indication on data sheet)
① What is the possibility of operation if the DNC pin is connected (or touching) to GND? (Could the output voltage change or cause component failure?)
② What is the possibility of operation if the DNC pin is connected (or contact) to the VOUT voltage (for example, 0.85 V or 1.8 V)? (Could the output voltage change or cause component failure?)
2) TT pin (not open on datasheet)
① What is the possibility of operation if the TT pin is open (floating)? (Could the output voltage change or cause component failure?)
② What is the possibility of operation if the TT pin is connected (or touching) to GND? (Could the output voltage change or cause component failure?)
③ What is the possibility of operation if the TT pin is connected (or contact) to the VOUT voltage (for example, 0.85 V or 1.8 V)? (Could the output voltage change or cause component failure?)
3) SS/TR pin
① What is the possibility of operation if the SS/TR pin is connected (or touching) to GND? (Could the output voltage change or cause component failure?)
② What is the possibility of operation if the SS/TR pin is connected (or contact) to the VOUT voltage (for example, 0.85 V or 1.8 V)? (Could the output voltage change or cause component failure?)
4) RT/CLK pin (when used in RT mode)
① What is the possibility of operation if the RT/CLK pin is left open (floating)? (Could the output voltage change or cause component failure?)
② What is the possibility of operation if the RT/CLK pin is connected (or touching) to GND? (Could the output voltage change or cause component failure?)
③ What is the possibility of operation if the RT/CLK pin is connected (or contact) to the VOUT voltage (for example, 0.85 V or 1.8 V)? (Could the output voltage change or cause component failure?)
Your advice is appreciated.
Best Regard,
Akihisa Tamazaki
