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.
When protecting single cell Li-ion portable devices such as cellphones or PDAs, the 2nA leakage current ensures virtually zero impact to battery life.
Together with a 2.5 to 7V operating range, these features allow the SP619 to improve system reliability and provide load switching in lithium-ion battery charging systems, low power USB clients, and low power distributed systems.
"Sipex recognises the growing need for greater system reliability and longer battery life in today's portable application market".
"By offering load protection and near zero leakage current, the SP619 represents a highly effective solution for a wide range of portable battery-powered devices", says Rich Kapusta, Sipex's Vice President for Interface Products.
"The SP619 further augments Sipex's portfolio in the portable applications space".
SP619 is available in RoHS/Pb-free 6-pin SOT-23 packages in the industrial temperature range.
Pricing for these products begins at US $0.25 in 1000 piece quantities.
