Induction cooker HK358M integrated circuit functions as follows:
Induction cooker HK358M is LM358 dual operational amplifier. The internal includes two independent, high-gain, internally frequency-compensated dual operational amplifiers, suitable for single-supply use with a wide supply voltage range, as well as for dual-supply operation mode, where the supply current is independent of the supply voltage under recommended operating conditions.
Its range of use includes sensing amplifier, DC gain module and all other single power supply of the use of operational amplifier occasions, in the middle of the induction cooker wire pan, equipped with a thermistor temperature sensor, its role is in the case of dry burning pot, play overtemperature protection, to prevent the stove surface due to dry burning fire. In order to allow the sensor to quickly sense the temperature of the microcrystalline plate, the thermistor is coated with thermal silicon.
