4 Device Comparison

Device Decoder shows some of the device naming nomenclature of the TPS371K-Q1 adjustable option. Not all device namings follow this nomenclature table. For a detailed breakdown of every adjustable and fixed voltage threshold variant see Device Nomenclature for more details. Contact TI sales representatives or on TI's E2E forum for detail and availability of other options.
TPS371K-Q1
  1. Not all TPS371K-Q1 devices can be decoded by this table. Refer to Device Nomenclature for a decoding table by part number and for fixed threshold variants.
  2. For 400V TPS371K-Q1, the undervoltage threshold can be between 180V to 300V and overvoltage can be between 440V to 540V.
  3. For 800V TPS371K-Q1, the undervoltage threshold can be between 360V to 600V and overvoltage can be between 860V to 1080V.
  4. For 1200V TPS371K-Q1, the undervoltage threshold can be between 540V to 900V and overvoltage can be between 1290V to 1500V.
