Vishay 2 V supply option optoelectronics series

Vishay has broadened its optoelectronics portfolio with the introduction of a ‘V’ low-voltage supply option for 10 of its TSOP IR series receivers.

The V series devices operate with a stable sensitivity rating at a low supply voltage down to 2 V over a temperature range of +5 to +85 °C.

In two-cell alkaline battery applications, a typical discharge curve under a 160 mA load goes from 3 V down to 2.5 V after about three hours of operation. This would represent the end of life for a standard receiver operating down to 2.5 V.

The typical non-linear battery discharge curve then provides a further 13 hours of operation before reaching 2 V. Thus a receiver capable of operating to 2 V can extend the useful battery life by a factor of more than four.

Typical end products for the series include small handheld battery-powered systems such as digital still cameras, bidirectional remote controls and 3D goggles. For additional power savings in battery-powered systems, the receivers feature a stand-by function.
