NVE Introduces IL4822 Isolated RS-485/RS-422 Transceiver
With Integrated 3.3-to-5 Volt DC-to-DC Boost Convertor
EDEN PRAIRIE, Minn.September 20, 2021NVE Corporation today introduced the IL4822 isolated RS-485/RS-422 transceiver with an integrated 3.3-to-five volt isolated DC-to-DC boost convertor. It is ideal for interfacing 3.3-volt controllers to ubiquitous five-volt busses. The new part complements the previously-announced IL4622E, which has a 3.3-to-3.3 volt DC-to-DC convertor for interfacing to newer 3.3-volt busses.
The new part is based on the revolutionary IsoLoop® DC-to-DC convertor technology first introduced in ILDC11xxx stand-alone isolated DC-to-DC convertors.
Key IL4822 features include:
250 mW 3.3-to-5 volt DC-to-DC boost convertor
40 Mbps RS-485 or RS-422 data rate
1 mVp-p DC-to-DC output ripple
2.5 kVrms isolation for both the transceiver and DC-to-DC convertor modules
JEDEC-standard wide-body SOIC with true 8 mm creepage
The 250 milliwatt integrated DC-to-DC boost convertor has enough current to power a single bus node or multiple nodes.
The IL4822 is rated at a best-in-class 40 megabits per second for high speed, long transmission distances, and high signal fidelity RS-485 or RS-422 data transmission..
One millivolt peak-to-peak ripple on the DC-to-DC convertor output is an order of magnitude less than conventional parts and means low noise and reliable systems.
Both the transceiver and DC-to-DC convertor modules are rated for full 2.5 kilovolts RMS isolation. The parts are VDE V 0884-11 certified under the stringent new IEC 60747-17 requirements, and UL1577 registered.
The new part is packaged in JEDEC-standard 16-pin wide-body packages with true 8 millimeter creepage in accordance with IEC60601.
Frequency hopping and integrated shielding provide the lowest EMI in the industry.
Low Parts Count
The integrated DC-to-DC convertor requires no additional regulation and ferrite beads are not necessary for EMI mitigation.
The IL4822 and IL4622 are in stock for immediate delivery. At $6.00 each in 1000-piece quantities, the new part is attractively priced, especially compared to using separate components.
