TPT71044-SOAR

Drivers, Receivers, Transceivers Overview

The TPT71044-SOAR is an isolated CAN transceiver from the TPT710xx family, designed for high-speed Controller Area Network (CAN) physical layer applications. It supports CAN FD and data rates up to 5 Mbps with a typical loop delay of 110 ns. The device features a 2.25 V to 5.5 V IO interface powered by VCCA and a 4.5 V to 5.5 V bus side powered by VCCB. It provides up to 5-kV RMS isolation rating in WSOP packages and ±200-kV/μs typical static common-mode transient immunity (CMTI). The component includes robust protection mechanisms such as ±42 V bus fault protection, ±15-kV IEC ESD protection on bus pins, and overtemperature shutdown. It operates within a junction temperature range of −40°C to 150°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure that the selected variant matches the required isolation voltage ratings and safety certifications for the target application environment. Cross-reference pin configurations carefully, as variations exist between different package options within the same product family.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring galvanic isolation in CAN bus systems operating at speeds up to 5 Mbps. Consider the thermal resistance characteristics when designing heat dissipation strategies, especially for high ambient temperatures. Verify compatibility with the microcontroller logic levels, noting the wide input voltage range supported by the TXD pin. Evaluate the need for specific safety certifications such as VDE or UL based on end-product regulatory requirements.

Drivers, Receivers, Transceivers Part Context

The TPT71044 belongs to the TPT710xx series of isolated CAN transceivers manufactured by 3PEAK. This family utilizes proprietary capacitive isolation technology to provide signal transmission across the isolation barrier. The TPT71044 differs from the TPT71050 primarily in the pin arrangement of the TXD and RXD terminals. Both variants share identical electrical performance characteristics and isolation capabilities.
