LM25066IA: is LM25066IAPSQX/NOPB P2P and equivalent to LM25066PSQX/NOPB?

Part Number: LM25066IA
Other Parts Discussed in Thread: LM25066I, LM25066A, LM25066,

My customer is wondering if  LM25066IAPSQX/NOPB can be used P2P instead of LM25066PSQX/NOPB.

  • Thanks for reaching out.

    All the variants of LM25066 are pin to pin compatible. 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 the most recent diagnostic and telemetry information in a single transaction. A few modifications on the firmware would be required, no hardware modification is necessary.
