NCV7344MW3T1G

Drivers, Receivers, Transceivers Overview

The NCV7344MW3T1G is a high-speed, low-power CAN and CAN FD transceiver manufactured by onsemi. It serves as the interface between a CAN protocol controller and the physical bus, providing differential transmit and receive capabilities. The device supports data rates beyond 1 Mbps to meet CAN flexible data rate requirements. It features a DFN-8 (3x3) wettable flank package with an exposed pad. Key electrical parameters include a supply voltage range of 4.75 V to 5.25 V for VCC and 2.8 V to 5.5 V for VIO. The operating temperature range is -40°C to +150°C. It includes a TxD dominant timeout function, thermal protection, and bus pin short-circuit proofing.

Drivers, Receivers, Transceivers Feature Summary

• Compatible with ISO 11898-2:2016 standard
• Very low current standby mode with wake-up capability via the CAN bus
• Low electromagnetic emission (EME) without requiring a common-mode choke
• High ESD robustness with greater than 8 kV system ESD pulse protection

Drivers, Receivers, Transceivers Applications

• Automotive HS-CAN networks
• Industrial networks
• Nodes requiring low-power modes with bus wake-up

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, filter time settings, and shipping configuration. Ensure the component meets AEC-Q100 qualification requirements for automotive applications. Confirm that the wettable flank package variant is selected if enhanced optical inspection is required for the assembly process.

Drivers, Receivers, Transceivers Selection Notes

Select the NCV7344MW3T1G when direct interfacing with 3 V to 5 V microcontrollers is necessary, as indicated by the '3' suffix denoting the VIO pin functionality. Choose this part over versions with long filter times if faster wake-up detection is required. Consider the DFN-8 package dimensions and thermal resistance characteristics for PCB layout planning in space-constrained designs.

Drivers, Receivers, Transceivers Part Context

The NCV7344MW3T1G belongs to the NCV734x family of stand-alone CAN transceivers from onsemi. This series complements previous generations such as AMIS42665 and AMIS3066x. The NCV prefix indicates that the device is qualified for automotive applications and requires unique site and control change requirements, ensuring compliance with PPAP standards.
