Firmenblog über Mingjiada Stock Supply of 3PEAK CAN Transceivers: TPT1445, TPT1051, TPT1255

Against the backdrop of accelerating domestic substitution in automotive networking and industrial communication systems, CAN transceivers—as key interface devices connecting controllers to physical buses—play a critical role, with their supply chain stability and product maturity directly impacting project delivery schedules. Mingjiada Electronics has long supplied the full range of 3PEAK CAN transceivers, covering both automotive-grade AEC-Q100-certified models and industrial-grade high-reliability models, providing stock availability to customers in automotive electronics, industrial control servos, energy storage systems, and communication base stations.

3PEAK CAN Transceiver Product Matrix: From Classic CAN FD to CAN SIC

Focusing on CAN physical layer transmission and reception requirements, 3PEAK has established a comprehensive product line covering different speed tiers, low-power modes, and ringing suppression capabilities. Furthermore, the entire series of automotive-grade CAN & LIN transceivers has achieved mass production through a fully domestic supply chain.

Automotive-Grade CAN FD Transceivers (AEC-Q100 Grade 1)

The TPT1044xQ series is Siripu’s flagship CAN FD transceiver for the automotive electronics market. It supports data rates up to 8 Mbps, complies with the ISO 11898-2:2024 standard, features bus fault protection up to ±45 V, and has an I/O voltage range from 1.7 V to 5.5 V, making it directly compatible with 1.8 V, 3.3 V, and 5 V MCU interfaces. This series supports Standby mode with a static current as low as 300 nA, making it suitable for body control and powertrain systems that are sensitive to sleep-mode power consumption.

The TPT1445Q series is Siripu’s new generation of automotive-grade CAN transceivers, which also supports 8 Mbps CAN FD and the ISO 11898-2:2024 partial networking feature. With a VIO level range of 1.7 V to 5.5 V, it eliminates the need for external level-shifting chips and has passed the German C&S conformance test. Its internal registers are fully hardware and software compatible with the TPT1145, facilitating seamless upgrades for existing platforms.

The TPT1043AQ supports Sleep mode, the TPT1057xQ supports Silent mode, and the TPT1462xQ/TPT1463Q further integrate CAN SIC ringing suppression functionality, making them suitable for optimizing signal integrity in complex in-vehicle network topologies.

Industrial-Grade, High-Reliability CAN Transceivers

The TPT1051 series (TPT1051H/TPT1051HV/TPT1051Q) supports 5 Mbps CAN FD communication, with bus fault protection voltage extended to ±70 V. It features integrated level shifting, short-circuit protection, thermal shutdown, and TXD high-level timeout functions, and operates within a temperature range of -40°C to +125°C.

The TPT1255/TPT1256 series are ruggedized industrial-grade 5 V CAN transceivers that support 5 Mbps CAN FD. They feature high common-mode rejection, high voltage withstand, and high ESD protection ratings, with a VCC input range of 4.5 V to 5.5 V and support for 3.3 V to 5 V VIO levels. These devices are designed for industrial control and communication equipment operating in complex electromagnetic environments.

The TPT133X series is compatible with ISO 11898-2:2016, supports 3.3 V power supply and 5 Mbps CAN FD, and integrates multiple fault protection functions. It is widely used in industrial automation, communication base stations, energy storage systems, and power system terminals.

Why Choose Siripu CAN Transceivers from Mingjiada

Reliability of the domestic supply chain. Siripu’s automotive-grade CAN transceivers have achieved mass production through a fully domestic supply chain. Next-generation products such as the TPT1445Q are manufactured entirely in China—from wafer fabrication to packaging and testing—effectively reducing the risk of supply disruptions caused by geopolitical and logistical fluctuations. As a long-standing spot supplier specializing in interface and driver components, Mingjiada is able to provide customers with stable, batch-based supply during this window of domestic production.

Broad Product Selection. From classic 5 Mbps CAN FD to 8 Mbps CAN SIC, and from low-power modes such as Standby, Silent, and Sleep to specific frame wake-up and ringing suppression, Siripu’s CAN transceiver product line offers a tiered range of options in terms of data rate, power consumption, protection level, and package size. This allows engineers to flexibly match components to node requirements in platform-based designs, rather than being forced to compromise among a limited number of models.

Typical Application Scenarios

Siripu CAN transceivers have been deployed in volume in the following fields:

Automotive Electronics: Body Control Module (BCM), Battery Management System (BMS), Motor Controller, ADAS sensor nodes, in-vehicle infotainment and instrument clusters, chassis and steering systems.

Industrial Automation: Industrial servo drives, PLC communication interfaces, sensor modules, industrial drones.

Communications and Energy: Communication base stations, energy storage system (BMS) communications, and power system protection devices.

Mingjiada Electronics can assist with product selection comparisons and sample support across the TPT1044xQ, TPT1445Q, TPT1051, and TPT1255 series based on specific project requirements for data rates, power supply architecture, sleep strategies, and packaging constraints.
