Upgraded series of IR receiver modules with new in-house IC

Vishay Intertechnology, Inc. has upgraded its TSOP18xx, TSOP58xx, and TSSP5xx series of IR receiver modules for remote control, proximity sensing, and light barrier applications. Supplied in Minicast packages, the enhanced solutions offer drop-in, plug-and-play replacements for existing devices in the series while providing 50% lower current consumption, improved ESD robustness to 12kV, a wider supply voltage range from 2V to 5.5V, 20% higher dark-ambient sensitivity, and improved performance under strong DC light.

Devices in the Vishay Semiconductors TSOP18xx, TSOP58xx, and TSSP5xx series each comprise a photodetector, preamplifier circuit, and IR filter in a single package. With their decreased current consumption over a wider voltage range, the receiver modules improve battery life in mobile devices, while their robustness under bright sunlight allows outdoor applications. By upgrading the IR receivers with its latest in-house IC technology, the company is ensuring its customers' long-term availability of the products – with reduced lead times. As drop-in replacements for existing devices, the modules help save costs by removing the necessity for PCB redesigns.

The TSOP18xx and TSOP58xx series are designed for IR remote control in televisions, soundbars, video game systems, STBs, appliances, air conditioners, and more. The devices provide increased robustness against disturbances such as IR emissions from different kinds of lamps for the remote control function in these products. Also, the modules are insensitive to supply voltage variations and ripple noise. The devices are available with carrier frequencies from 30kHz to 56kHz and in six AGC versions for short and long burst codes.

The TSSP5xx series fixed-gain IR receiver modules deliver long-range proximity and presence sensing to 2m and can be paired with the TSAL6200 emitter for light barrier applications up to 8m (TSSP580xx). Sensitive to a carrier frequency of 38kHz – and offering a peak sensitivity of 940 nm – the devices are excellent for sensing the distance to objects for toys, drones, and robots; object approach detection for the activation of displays and user consoles; and garage door light barriers. They may also be employed as reflective sensors for hand dryers, towel or soap dispensers, water faucets, toilets, vending machine fall detection, and security and pet gates.
