Diodes offers both fixed and adjustable universal timer ICs for home appliance applications having an AC power source and needing to directly drive either an external relay or silicon-controlled rectifier (SCR). These timer ICs are ideal for low cost, high volume applications such as home appliances, healthcare products, and industrial control systems, among others.
Universal timer ICs play an important role in creating more power efficient systems in appliances like irons, electric kettles, heaters, toasters, and coffee machines. Timers built into these products can automatically shut them off after a set usage period to prevent them from continuing to draw power when they are not in use. Timers can also improve safety by enabling robust power safety controls that can turn off systems to prevent injury to users or damage to equipment.
Diodes’ universal timers are standard ASIC products with integrated application-specific functionality to minimize cost, reduce design complexity, and speed time-to-market. Products range from simple timers to multi-functional devices with a wide selection of advanced capabilities, depending upon the family:
Diodes also provides a variety of application-specific reference circuits to accelerate design of your home appliance, healthcare product, or industrial control system. These proven solutions meet the Energy-related Products (ErP) European directive by operating at less than 0.5 W power consumption when in standby mode. Designs are available that support both 110 V and 220 V AC power source input. Diodes has been a leader in the home appliance industry for more than a decade and has experienced design teams available to assist you with design, production, and certification issues.
Not all obsolete parts will have a direct replacement. However, we recommended that you contact your regional sales office.
There are several types of jitter, but the main ones are: cycle-to-cycle jitter, period jitter, half period jitter, and peak-to-peak jitter. Jitter terminology can be found in AB36: Jitter Measurement Techniques at Application Brief No. 36 or Application Note No. 27.
