Temperature sensors are used in high-power switching power supply designs and need to monitor power transistors and heat sinks. Common temperature measurement methods use negative temperature coefficient (NTC) thermistors or positive temperature coefficient (PTC) silicon-based thermistors. However, whether using NTC or PTC, an ADC and an MCU are required to measure the voltage output of the thermistor.

The following is an introduction to silicon-based thermistors with a positive temperature coefficient (PTC).

TMP61 ±1% 10kΩ Linear Thermistor in 0402 and 0603 Package Options

Silicon-based thermistor with positive temperature coefficient (PTC) Linear resistance change with temperature 10kΩ nominal resistance (R25) at 25°C – ±1% maximum (0°C to 70°C) Wide operating temperature range of –40°C to +125°C Stable sensitivity over temperature range – 6400ppm/°C TCR (25°C) – 0.2% typical TCR tolerance over temperature range Fast thermal response time of 0.6s (DEC) Long life and robust performance – Built-in fail-safe to protect against short-circuit faults – Typical 0.5% long-term sensor drift
