  • 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
  • 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
  • Short-circuit Failure Analysis for the Relay Contact at the Input of Switching Power Supply
    An important performance index of switching power supply is input inrush current, which is usually designed as small as possible. The conventional design is to connect a thermistor (NTC) in series on the live wire at the input of the switching power supply. While for switching power supply
  • 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
