Vishay Intertechnology, Inc. has announced upgrades to its TSOP18xx, TSOP58xx, and TSSP5xx series of infrared (IR) receiver modules designed for remote control, proximity sensing, and light barrier technology applications. These solutions, available in Minicast packages, offer replacements for existing devices within the series. They bring improvements, including reduced current consumption, enhanced ESD robustness, a supply voltage range from 2.0 V to 5.5 V, increased dark-ambient sensitivity, and improved performance in intense DC light.

The modules incorporate a photodetector, preamplifier circuit, and IR filter within a single package. With their lowered current consumption and extended voltage range, these receiver modules contribute to battery life in mobile devices. Furthermore, their resilience in sunlight makes them suitable for outdoor applications. Vishay’s commitment to upgrading these IR receivers ensures the availability of these products with reduced lead times, benefiting its customers. Moreover, as direct replacements for existing devices, these modules eliminate the need for costly PCB redesigns, resulting in cost savings.

Both series are tailored for IR remote control applications in devices such as televisions, soundbars, video game systems, set-top boxes (STBs), appliances, and air conditioners. These devices offer robustness against disturbances like IR emissions from lamps. Additionally, they remain unaffected by supply voltage variations and ripple noise. The modules come with carrier frequencies ranging from 30 to 56 kHz and are available in six automatic gain control (AGC) versions, accommodating short and long burst codes.

The TSSP5xx series delivers IR receiver modules suitable for proximity and presence sensing, extending up to 2 meters. These devices are sensitive to a carrier frequency of 38 kHz and offer peak sensitivity at 940 nm. They are suitable for various applications, including sensing the distance to objects in toys, drones, and robots, detecting object approaches for display, and activating user consoles. They can also be used in scenarios such as garage door light barriers, reflective sensors for hand dryers, towel or soap dispensers, water faucets, toilets, vending machine fall detection, security systems, and pet gates.
