TPT71044-SOBR

Drivers, Receivers, Transceivers Overview

The TPT71044-SOBR is an isolated CAN transceiver from the TPT710xx family, manufactured by 3PEAK. It complies with the ISO11898 High-speed CAN standard and supports CAN FD data rates up to 5 Mbps. The device features a typical loop delay of 110 ns and operates with a VCCA supply range of 2.25 V to 5.5 V and a VCCB supply range of 4.5 V to 5.5 V. It provides a receiver common-mode input voltage range of ±30 V and bus fault protection up to ±42 V. The component offers up to 5-kV RMS isolation rating in WSOP packages, with static CMTI typically at ±200 kV/μs and dynamic CMTI at ±150 kV/μs. Junction temperatures are supported from −40°C to 150°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (WSOP8 or WSOP16) required for the design, as pin configurations differ between TPT71044 and TPT71050 models. Confirm that the ordering suffix matches the desired tape and reel packaging format. Ensure all safety-related certifications such as VDE, UL, and CSA align with the target market regulatory requirements before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select the TPT71044 when the TXD and RXD pin positions match the existing PCB layout constraints. Choose this model if the application requires operation within the specified 2.25 V to 5.5 V logic interface range. Verify that the system can accommodate the separate VCCA and VCCB power domains, as the device requires distinct supplies for the I/O side and the CAN bus side respectively.

Drivers, Receivers, Transceivers Part Context

The TPT71044 belongs to the TPT710xx series of isolated CAN transceivers designed for robust communication in noisy environments. This family utilizes ON-OFF Keying modulation to transmit data across the isolation barrier. The TPT71044 specifically distinguishes itself from the TPT71050 through its unique pin mapping for the TXD and RXD terminals, while sharing identical electrical performance characteristics and isolation capabilities.
