Vishay Intertechnology announced that the company has upgraded its TSOP2xxx, TSOP4xxx, TSOP57xxx, TSOP6xxx and TSOP77xxx series infrared (IR) receiver modules for IR remote control applications with a new Cyllene 2 IC.
Designed in-house to ensure long-term product availability and reduced lead times, the new IC allows designers to achieve greater performance with drastically reduced current consumption across a wider voltage source – while also offering greater robustness against ESD and direct sunlight.
Vishay's new semiconductor receivers are designed for IR remote control in consumer televisions, set-top boxes (STBs), audio and gaming systems, air conditioners and other appliances, as well as industrial automation controls, lighting systems and more.
For these products, the devices provide immunity against disturbances such as IR emissions from CFL bulbs and RF emissions from integrated Wi-Fi antennas.
Providing designers with plug and play replacements for original receiver modules, the improved devices offer 50% lower current consumption, up to 0.35 mA typical over a supply voltage range of 2.0 to 5.5 V – increasing life battery life in mobile consumer electronics such as robotic vacuum cleaners.
For increased reliability, the devices offer increased ESD withstand capability up to 12 kV (human body model), while their robustness in direct sunlight results in improved performance for outdoor applications such as light barriers on garage doors.
To simplify designs, the receivers feature a photodetector, preamplifier circuit, and IR filter in a single epoxy Mold (TSOP2xxx and TSOP4xxx), Belobog (TSOP57xxx), Panhead (TSOP6xxx), or Heimdall (TSOP77xxx) package.
The devices are available with carrier frequencies from 30 kHz to 56 kHz and different versions of automatic gain control (AGC) for long or short burst codes. RoHS compliant, halogen-free and Vishay Green, the receivers offer excellent noise ripple immunity.
Samples and production quantities of the upgraded IR receiver modules are now available, with lead times of eight weeks.
