4 Device Comparison

Figure 4-1 shows some of the device naming nomenclature of the TPS37100 and TPS37102. Not all device namings follow this nomenclature table. For a detailed breakdown of every device part number by features, thresholds, and analog out scale see Table 4-1 for more details. Contact TI sales representatives or on TI's E2E forum for detail and availability of other options.

  1. For listed percentage denotes hysteresis tolerance, see Section 6.5 for more information
  2. VITN or VITP threshold with ADJ denotes an adjustable voltage threshold set by an external resistor divider, see Section 7.3.2.1 for more information on how to set the threshold.

  1. Refer to Table 4-1 for a decoding table by part number.
  2. Adjustable OV or UV only options threshold is 800mV.
  3. Adjustable Window option thresholds are centered around 800mV.
    1. Example: TPS37100W41xDYYR is a ±4% adjustable window device.
      1. Equation 1. Overvoltage threshold: 800mV × (1 + 0.04) = 832mV
      2. Equation 2. Undervoltage threshold: 800mV × (1 − 0.04) = 768mV
  4. OUT A/B standard is available for OV only, UV only, and window. OUT A/B Combined is only available for window. Refer to Section 7.3.3.
