Temperature Control

This family presents a range of zero crossing triac control integrated circuits designed for various heating/cooling operations with a single or multiple feedback control. Choose from either a simple On/Off or proportional controller integrated circuits to meet your thermostatic needs. These integrated circuits require only low external component count and have wide operating temperature control range.

In particular the OM1654A and IES5521A are well suited for hair styling tools. Featuring simple zero crossing triac triggering with minimal external components they are ideal for small board space in hair straighteners and curling irons. Additional features such as time out timer as safety feature is also available in some integrated circuits.
