Thermistors are a type of sensitive components, which are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to their temperature coefficients. The typical characteristic of thermistors is that they are sensitive to temperature and show different resistance values at different temperatures. The higher the temperature, the greater the resistance value of the positive temperature coefficient thermistor (PTC), while the higher the temperature, the lower the resistance value of the negative temperature coefficient thermistor (NTC). They are both semiconductor devices.

Kote Polymer PTC solves the problem of overcharge short circuit protection of lithium-ion batteries
Although primary protection is generally considered reliable, the protection IC or MOS-FET may be damaged when the electrostatic discharge voltage is too high or the temperature is too high, and the integrated circuit will oscillate when short-circuited. At the same time, most IC+MOS-FET circuits detect charging and di
