Other Parts Discussed in Thread: TPS62901, TPS62901-Q1
Hello team,
My customer has questions because they would like to confirm how TPSM82901 behaves and whether it is dangerous or not.
1) SW/NC pin (open instruction on data sheet)
① What is the possibility of operation if the SW/NC 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 SW/NC 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) MODE/S-CONF pin (not open on datasheet)
① What is the possibility of operation if the MODE/S-CONF pin is left open (floating)? (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) FB/VSET pin (if MODE/S-CONF is connected to HI)
① What is the possibility of operation if the FB/VSET pin is left open (floating)? (Could the output voltage change or cause component failure?)
② What is the possibility of operation if the FB/VSET pin is connected (or touching) to GND? (Could the output voltage change or cause component failure?)
Your advice is appreciated.
Best Regard,
Akihisa Tamazaki
