Advanced 5V transceivers for RS-485 networks
A family of advanced 5V RS-485 transceivers has 15kV ESD protection, hot-swap capability, advanced failsafe protection, voltage and thermal overload protection, and shutdown.
Operating at an industry leading 2.4MHz switching frequency, the SP7686 requires only four small external components further reducing the overall solution footprint to new levels.
SP7686 features a typical 3.5s timeout in flash mode which prevents the LED from overheating during long operating duty cycles.
The programmable LED current also allows designers to reduce currents as the battery gets low to prevent false system resets thus extending useful battery life.
The family also includes the SP7686A which eliminates the single wire interface but provides two separate control pins for enable and torch/flash select.
The flash current is preset to 400mA, and the torch current is set to 150mA.
These LED flash drivers enable a wide range of LED lighting applications with minimum external components require and completely effortless design in today's application.
Both products offered in a tiny 2 x 3mm DFN package making them the smallest single-wire control LED drivers on the market today.
"SP7686 delivers the smallest solution size, design simplicity, and programmable LED current making the SP7686 and SP7686A an excellent choice for cellphone designers and others engineers using LED lighting", said Chris Lee, Technical Marketing Manager.
"Sipex is committed to providing product solutions and features that support the latest LED technology".
The SP7686 and SP7686A are available in Pb-free, thermally enhanced 8-pin 2 x 3mm DFN packages and are specified over the -40 to +85C temperature range.
Pricing for these products begins at US $1.25 in 1000-piece quantities.
