TPT1051H-SO1R-S

Drivers, Receivers, Transceivers Overview

The TPT1051H-SO1R-S is a high-speed CAN transceiver compliant with ISO 11898-2:2016 and SAE J2284 standards, supporting CAN FD data rates up to 5 Mbps. It operates on a 4.5 V to 5.5 V VCC supply with an I/O range of 2.8 V to 5.5 V. The device features ±70 V bus fault protection, ±30 V common-mode input voltage, and IEC 61000-4-2 ESD protection up to ±15 kV. Key electrical parameters include a typical propagation delay of 60 ns, total loop delay of 110 ns, and dominant short-circuit output current limits of ±115 mA. It includes silent mode control via the S pin and TXD dominant time-out functionality.

Drivers, Receivers, Transceivers Feature Summary

• Supports CAN FD networks with enhanced timing margins for long and highly loaded systems
• Provides robust fault protection including crosswire, overvoltage, and loss of ground from -70 V to +70 V
• Features ideal passive behavior to the CAN bus when unpowered
• Includes silent (listen-only) mode and TXD dominant time-out function to prevent network blockage

Drivers, Receivers, Transceivers Applications

• Highly loaded CAN networks in industrial automation and sensor systems
• Building and security control systems
• Energy storage systems
• Telecom base station status and control

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SO1R-S' corresponds to the SOP-8 package and tape-and-reel packaging format as documented in the official datasheet. Confirm that the 'H' variant designation indicates the absence of the secondary VIO power supply pin compared to the 'HV' version. Ensure compatibility with the required operating temperature range of -40°C to +125°C for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select the TPT1051H-SO1R-S when a single 5 V supply is sufficient for both the transceiver core and I/O logic levels, eliminating the need for a separate VIO supply rail found in the HV variant. This part is suitable for applications requiring silent mode operation and robust bus fault protection up to ±70 V. Verify that the MCU interface voltage falls within the supported 2.8 V to 5.5 V range for proper signal integrity.

Drivers, Receivers, Transceivers Part Context

The TPT1051H belongs to the TPT1051 family of fault-protected high-speed CAN FD transceivers manufactured by 3PEAK. It shares functional similarities with the TPT1051HV but lacks the dedicated VIO pin, integrating the I/O level shifting internally to the VCC supply. This simplifies the external circuit design for standard 5 V or 3.3 V logic interfaces while maintaining compliance with ISO 11898-2 physical layer standards.
