Applications
The LTM2882CY-3#PBF is used in industrial control systems and PLCs where RS-232 serial ports must be galvanically isolated from high-voltage machinery, protecting the host MCU from ground loops and transients exceeding 1 kV. Medical devices leverage its 2.5 kV RMS isolation to meet IEC 60601 patient-isolation requirements on diagnostic instrument serial links. It is also deployed in factory automation equipment and remote sensor interfaces where a single compact µModule replaces multiple discrete isolation ICs, transformers, and power supply components.

Frequently Asked Questions
How does the LTM2882CY-3#PBF achieve galvanic isolation without external transformers in a PLC serial port design?
The device integrates both signal isolation and an isolated DC-DC converter inside a single BGA-32 µModule, providing 2.5 kV RMS isolation across the RS-232 interface barrier without requiring any external transformer, charge pump, or additional isolation power supply, reducing BOM by up to 10 components.
What isolation voltage rating does the LTM2882CY-3#PBF provide and which safety standards does it help meet for medical equipment?
The LTM2882CY-3#PBF is rated for 2.5 kV RMS continuous isolation, supporting compliance with IEC 60601-1 for medical electrical equipment patient-protection requirements on serial communication ports connecting diagnostic instruments to hospital network or data acquisition systems.
For a compact industrial RS-232 node, how many external components does the LTM2882CY-3#PBF require?
Because the µModule integrates drivers, receivers, and isolated power, a typical RS-232 port implementation needs only a small number of bypass capacitors—often 4 or fewer—reducing a traditional 15-component discrete design to under 10 mm x 10 mm on a PCB with 2-driver, 2-receiver functionality.
How does the Schmitt-trigger input characteristic of the LTM2882CY-3#PBF improve reliability on long RS-232 cable runs?
The Schmitt-trigger inputs add hysteresis of typically 0.5V, preventing false toggling from noise or slow edges on RS-232 cables longer than 15 m in electrically noisy factory environments, ensuring clean UART data recovery at the host MCU even at baud rates up to 120 kbps.
