| product overview |
A range of integrated circuits dedicated to thermostat management that could hold the key to solving your problem.
Hendon Semiconductors temperature control range of integrated circuits has been designed specifically to cover a wide range of simple, low cost thermostat applications with particular attention to increase performance and sensing capabilities. |
| OM1654A simple zero crossing triac control IC |
A simple to use, low cost triac control IC using a minimum number of external components. Featuring zero-crossing switching of resistive loads for low EMI. It is an ideal replacement for the traditional bimetallic switch.
Typical applications include hair styling tools (hair straighteners, curling irons), home appliances (electric iron) and kitchen appliances (electric fry pans, skillets, toaster ovens) |
| IES5521A simple zero crossing triac control with timeout timer |
In addition to the features of OM1654A, the IES5521A has an additional time out timer. Time out refers to the time allowed for operation before the IES5521A switches the heating control off providing a safety feature in many heating appliances. Different time out of less than 1 hour to over 5 hours is achievable with simple external RC components.
Typical applications include hair styling tools (hair straighteners, curling irons), home appliances (electric iron) and kitchen appliances (electric fry pans, skillets, toaster ovens) |
| OM1682A precision triac control thermostat IC |
A refined, accurate thermostat designed to be used in circuits that drive both inductive and resistive loads, where greater accuracy is required and external input/output access would be beneficial. OM1682A are accurate to 1% of temperature control range.
Typical applications include industrial control (refrigeration controllers, freezers), water heating, room heaters, ovens and underfloor heating. |
| OM1894 dual sensing precsion temperature control IC |
An accurate thermostat with smart triac drive designed for use in circuit applications with a need for 2 sense inputs and drive both inductive and resistive loads. This IC uses patented smart triac drive circuitry that minimises EMI filtering with inductive load. Accuracy and input/output flexibility are also built in.
Typical applications include water heating with humidity monitoring, water heating with level monitoring, thermal control with ambient temperature monitoring and refrigeration controllers. |
| OM1895 simmerstat control IC |
A simple to use, precision simmerstat control integrated circuit where a variable "On" period in a fixed cycle times, is required. The OM1895 has four versions of its fixed cycle time to meet EMC flicker regulations.
Typical applications include personal care appliances (electric blankets, heating pads), kitchen appliances (electric cook tops, electric stove) and speed control of fan motors.
Hendon Semiconductors temperature control integrated circuits features:-
- Excellent (zero crossing) triac drive operation for low EMI
- Single or multiple sensing capabilities
- Support thermocouple, NTC/PTC thermistor or RTD sensor
- Suited for wide temperature control range
- Mains voltage is determined by the selection of only one resistor value
- Simple design flow and ease of manufacture with minimum external components with no software or programming required

| IES5431 electronic dual blanket control IC |
IES5431 is a monolithic integrated circuit for duty cycle control designed specifically for electric blankets applications. It features independent control of two sections of the blanket from a single control IC, with the major part of the control function arising from the IES5431 built into the Master controller. |
