  • Transformer Inrush Current - Use an NTC Thermistor
    A transformer draws inrush current that can exceed saturation current affecting the magnetic property of the core. This happens even if the transformer is on no load with its secondary open. The magnitude of the inrush current depends on the instant on the AC wave at which the transformer is
  • Thermistor Temperature Sensing with MCP6SX2 PGAs
    This application note shows two designs that use a precise, negative temperature coefficient (NTC) thermistor for temperature measurement. The thermistor is placed in a resistive divider to linearize the temperature-to-voltage conversion. The voltage is processed in the analog domain by the MCP6SX2
  • Thermistor Temperature Sensing with MCP6S2X PGA
    This application note shows two circuits that use a precise, negative temperature coefficient (NTC) thermistor for temperature measurement. The thermistor is placed in a resistive divider to linearize the voltage response to temperature. This voltage is then processed in the analog domain
  • Special Thermistors Limit Inrush Current
    is a special type of negative temperature coefficient (NTC) thermistor.
  • Protecting Switching Power Supplies from Inrush Current
    This application note provides some design considerations for inrush current protection of the AC current applicable to Switching Power Supplies (SPS). The solution suggested in this application note uses an NTC Power Thermistor in separate legs of the power supply circuit (see Figure 1). This NTC
  • Thermistors in Single Supply Temperature Sensing Circuits
    focuses on circuit solutions that use Negative Temperature Coefficient (NTC) thermistors in the design. The Thermistor has a non-linear resistance change-over temperature. The degree of this non-linearity will be discussed in the "Hardware Linearization Solutions" section of this application note
