TPT7487-SOBR

Drivers, Receivers, Transceivers Overview

The TPT7487-SOBR is an isolated half-duplex RS-485 transceiver manufactured by 3PEAK in a WSOP16 package. It operates on a supply voltage of 3.0 V to 5.5 V with a data rate of 500 kbps. The device provides up to 5-kV RMS isolation rating and features ±200-kV/μs typical static common-mode transient immunity (CMTI). It includes hot-plug circuitry, full fail-safe receivers, and bus-pin protection rated at ±15-kV IEC 61000-4-2 contact discharge. The component supports up to 256 nodes on the network and is characterized for operation from −40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Isolated RS-485 transceiver with up to 5-kV RMS isolation rating
• Hot-plug capability keeping outputs in three-state during power-up/down
• Full fail-safe receiver ensuring logic high output when inputs are open or shorted
• Bus-pin protection against ±15-kV IEC 61000-4-2 contact discharge

Drivers, Receivers, Transceivers Applications

• Home Appliance
• Motor Drives
• Industrial Control
• Communication Infrastructure

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix SOBR corresponds to the tape and reel packaging configuration as documented in the manufacturer's order information table. Confirm that the green RoHS-compliant status aligns with project environmental requirements. Ensure the MSL3 classification matches the assembly process capabilities of the manufacturing facility.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring galvanic isolation between logic and bus domains in half-duplex RS-485 networks. The 500-kbps speed and 1/8 unit load capability support extensive node counts without repeaters. Verify that the required isolation voltage meets system safety standards, noting the 5000 VRMS UL 1577 certification for basic insulation.

Drivers, Receivers, Transceivers Part Context

The TPT7487 belongs to the 3PEAK isolated RS-485/RS-422 transceiver family, designed alongside the full-duplex TPT7488 variant. Both devices share similar electrical characteristics and packaging but differ in duplexing capability. This series utilizes proprietary isolation IP technology to provide robust performance in noisy industrial environments while maintaining compliance with international safety certifications.

Drivers, Receivers, Transceivers Replacement Considerations

The TPT7488-SOBR serves as a functional substitute if full-duplex communication is required instead of half-duplex. Other non-isolated RS-485 transceivers lack the galvanic isolation barrier and may not meet safety certification requirements for systems demanding 5-kV RMS isolation.
