TPT1042V-DF6R-S

Drivers, Receivers, Transceivers Overview

The TPT1042V-DF6R-S is a half-duplex CAN FD transceiver manufactured by 3PEAK, designed for high-speed Controller Area Network applications. It supports data rates up to 5 Mbps and complies with ISO 11898-2:2016 and SAE J2284 standards. The device operates on a 4.5 V to 5.5 V VCC supply and features a secondary VIO pin supporting 2.8 V to 5.5 V I/O levels. It provides ±70 V bus fault protection, ±30 V common-mode range, and IEC 61000-4-2 ESD protection up to ±15 kV. Packaged in an 8-lead DFN3x3-8L leadless format, it functions within an ambient temperature range of -40°C to +125°C.

• Field industrial automation, sensor, and driver systems
• Building and security control systems
• Energy storage systems
• Telecom base station status and control

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific part number suffix matches the required package type, as the 'DF6R' designation indicates the DFN3x3-8L leadless package. Confirm the presence of the 'V' suffix to ensure the inclusion of the dedicated VIO pin for independent I/O level shifting. Ensure the procurement order aligns with the manufacturer's standard tape and reel quantity specifications.

Drivers, Receivers, Transceivers Selection Notes

Select the TPT1042V variant specifically if the design requires a separate VIO supply pin to interface with microcontrollers operating at logic levels between 2.8 V and 5.5 V independently of the main VCC rail. If the MCU shares the same voltage domain as the transceiver power supply, the standard TPT1042 without the V suffix may be sufficient. Verify thermal requirements against the junction-to-ambient thermal resistance values provided in the datasheet.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TPT1042 family of fault-protected high-speed CAN FD transceivers from 3PEAK. The family includes SOP8 and DFN3x3-8L package options, with variants distinguished by the presence or absence of the VIO pin. All devices in this series are characterized for operation across the extended automotive-grade temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include TPT1042-DF6R-S (same package, no VIO pin) and TCAN1042GVDRBTQ1 (Texas Instruments, 8-VSON package). Verify pinout compatibility and electrical parameter alignment before substitution.

Drivers, Receivers, Transceivers FAQ

What is the function of the VIO pin on the TPT1042V?

The VIO pin serves as a secondary power supply input that allows for I/O level shifting. It enables the TXD input thresholds and RXD output levels to operate within a range of 2.8 V to 5.5 V, independent of the main VCC supply.

How does the device behave when unpowered?

The TPT1042V exhibits ideal passive behavior to the CAN bus when unpowered. This means it presents a high impedance to the bus lines, preventing interference with other active nodes on the network even when the device itself has no power.

What protection features are included for the CAN bus lines?

The device offers robust protection including ±70 V bus fault protection, ±30 V common-mode input voltage range, and IEC 61000-4-2 electrostatic discharge (ESD) protection rated up to ±15 kV for both contact and air-gap discharge.
