Part Number: LM75A

Hello E2E,

Our customer is trying the LM75 with there test board.
When they written 0x3C00 to Thyst register, the device output 0x3CFF when read.
Is it malfunction? Or is there a problem with how to use it?

Best regards,
ACGUY

Hello,

Thank you for posting to the Sensing forum.

If possible, please attach a logic analyzer or oscilloscope capture of the 0x3C00 write and 0x3CFF read. This will help us troubleshoot further.

Best regards,

Nicole
