Hi Team,

The customer is asking that what is the difference between LM25066PSQ/NOPB and LM25066IPSQX/NOPB ?
LM25066PSQ/NOPB is also rated at industrial temp -40 to 125c, the same as Industrial grade. Thank you.

Best regards,

Mike

Hi Mike,

Thanks for reaching out to us.

The key difference among LM25066I, LM25066A, LM25066IA, and LM25066 is telemetry accuracy. Please refer to the “Telemetry Accuracy” of “Electrical Characteristics” table in each datasheet for more details.

LM25066I and LM25066IA add the READ_EIN energy accumulator feature, other two don’t have this feature.

It’s recommended to use MFR_SPECIFIC_18: AVG_BLOCK_READ (E2h) and MFR_SPECIFIC_10: BLOCK_READ (DAh) block read commands to retrieve most recent diagnostic and telemetry information in a single transaction. This will make all the LM25066 variants to be completely software compatible.
