TJA1462ATK/0Z 개요
What is a CAN SIC transceiver? A Controller Area Network (CAN) transceiver is the physical-layer bridge between a CAN protocol controller (typically an MCU's CAN module) and the differential CAN bus. CAN SIC (Signal Improvement Capability) is an enhancement defined in ISO 11898-2:2024 that shapes the transmitted signal edges to reduce ringing on the bus, allowing larger topologies, longer stub lengths, and higher data rates on CAN FD networks. In the broader taxonomy: CAN transceiver -> CAN interface IC -> wireline transceiver -> interface IC -> semiconductor. The TJA1462 belongs to the TJA146x family that brings this signal-improvement behavior into mainstream automotive designs.
Key features highlighted in the verified web data include up to 8 Mbit/s data rate, a low-power Standby mode, a VIO supply pin for direct interfacing with 1.8V-5V MCUs, ISO 11898-2:2024 and SAE J2284-1..5 compliance, and an operating temperature range suitable for under-the-hood automotive use. The HVSON8 package has an exposed pad that improves thermal performance and shortens the ground return, both critical for EMI-sensitive automotive bus nodes.
Architecturally, the device integrates the physical bus drivers, slope control for SIC, dominant/recessive bit handling, and a low-power Standby state that can be commanded by the host. By meeting the latest ISO 11898-2:2024 third edition, it is forward-compatible with emerging CAN XL networks and protects existing designs from obsolescence.
Typical applications include automotive body and chassis ECUs, CAN FD gateways, powertrain nodes transitioning from classical CAN, industrial CAN FD backbones needing SIC behavior, and any design replacing older CAN transceivers with a Standby-capable SIC part.
When designing with this device, pay attention to bus termination (120 ohm at each end), common-mode choke selection, and decoupling of both VCC and VIO to minimize bus emissions. The VIO pin allows the TXD/RXD logic side to be powered at the same rail as the host MCU, eliminating level shifters.

일반적인 애플리케이션
TJA1462ATK/0Z 적합 용도: 6 애플리케이션s: Automotive Body and Chassis ECU, CAN FD Gateway Between Domains, Powertrain Node Transitioning from Classical CAN, Industrial CAN FD Backbone with SIC, Agricultural and Off-Highway Vehicle Networks, EV Charging Station Communication Module.
Automotive Body and Chassis ECU
The TJA1462ATK/0Z fits body and chassis ECUs (door modules, lighting controllers, mirror modules) where CAN FD networks run at 2-5 Mbit/s across multiple sub-nodes. Its ISO 11898-2:2024 SIC behavior reduces bus ringing so engineers can use longer stubs and looser topology rules, while the VIO pin interfaces directly to 1.8V-5V MCU CAN modules without a level translator. The HVSON8 footprint and AEC-Q100 qualification suit compact automotive PCBAs.
추천
CAN FD Gateway Between Domains
A central or zonal gateway translating between classical CAN, CAN FD and possibly CAN XL domains benefits from the TJA1462ATK/0Z's 8 Mbit/s capability and forward compatibility with ISO 11898-2:2024. The Standby mode lets the gateway quiesce sub-buses when the vehicle is parked, reducing quiescent current. Pairing it with a high-pin-count host MCU such as the SPC5607BF1VLU6R gives designers enough CAN channels and processing headroom for protocol translation.
추천
Powertrain Node Transitioning from Classical CAN
Powertrain ECUs (transmission, EPS, engine management) migrating from classical CAN to CAN FD use the TJA1462ATK/0Z as a future-proof physical layer. Its 8 Mbit/s ceiling supports emerging CAN FD use cases like on-board calibration and sensor aggregation, while its backward compatibility preserves operation on existing classical CAN segments during the transition. AEC-Q100 with 150C junction rating handles the harsh thermal environment under the hood.
추천
Industrial CAN FD Backbone with SIC
Industrial machinery, robots and PLCs adopting CAN FD often face long stubs and complex cable harnesses where ringing degrades classical transceivers. The TJA1462ATK/0Z's SIC capability allows CAN FD at 5 Mbit/s on these topologies without re-engineering the cable plant. The VIO pin simplifies interfacing with 3.3V industrial MCUs such as the STM32F429VGT6TR family. Standby mode supports low-power sleep states in battery-backed industrial nodes.
추천
Agricultural and Off-Highway Vehicle Networks
Tractors, construction equipment and off-highway vehicles run CAN bus topologies that are long and noisy due to chassis size and cable routing. The TJA1462ATK/0Z's SIC shaping and high common-mode tolerance help maintain signal integrity on these extended networks, while AEC-Q100 qualification (used broadly beyond strict automotive) supports the temperature extremes of off-highway operation. The HVSON8 package provides mechanical robustness through its leadless construction.
추천
EV Charging Station Communication Module
EV charging stations (AC and DC) often expose a CAN FD interface for charger-to-EV handshake, ISO 15118-20 power-line communication gating, and inter-module communication. The TJA1462ATK/0Z's 8 Mbit/s capability supports the higher throughput needs of modern charging protocols, while its AEC-Q100 rating ensures reliable operation across the wide environmental conditions of outdoor charging stations. The Standby mode enables low quiescent current in idle states.

설계 노트
Place the TJA1462ATK/0Z as close as possible to the bus connector and keep the CANH/CANL traces as a short, symmetric differential pair with 100-120 ohm differential impedance. Tie the HVSON8 exposed pad to a solid ground pour with multiple thermal vias. Place the VCC and VIO decoupling capacitors (typically 100nF ceramic plus 4.7uF bulk) within 3 mm of the respective supply pins to keep the bus-side and logic-side rails clean.
Power VCC from a clean 5V rail capable of supplying the bus's dominant/recessive current transitions (peak ~70 mA per node during arbitration). Power VIO from the same rail as the host MCU's CAN module (1.8V, 3.3V, or 5V) to eliminate level shifters. Add a ferrite bead or common-mode choke on the bus feed if the design must pass IEC 62228 Class A or B EMC compliance, especially on long stubs.
Do not omit the 120 ohm termination resistors at each end of the bus; stubs must remain short relative to the bit timing. Ensure the STB pin is driven to a defined logic level; a floating STB can leave the device in an undefined state and draw elevated quiescent current. When migrating from a non-SIC transceiver, leave headroom in the bit-timing configuration because SIC edges look slightly different at the receiver.
CAN SIC reduces but does not eliminate ringing; for very long stubs (above 10% of the bit time), still consider a small common-mode choke and verify with a bus-eye diagram. The TJA1462's transmit edge shaping follows ISO 11898-2:2024 third edition, so confirm the rest of your bus nodes either support SIC or are guaranteed compatible (per SAE J2284-1..5) before mixing on the same segment.
