UJA1169ATK/3Z - Mini HS-CAN SBC, 3.3V/250mA, AEC-Q100 | NXP
MPN: UJA1169ATK/3Z ✓ Hoạt độngUJA1169ATK/3Z Tóm tắt
What is a CAN System Basis Chip (SBC)? An SBC is a highly integrated mixed-signal IC that combines a CAN (Controller Area Network) or CAN FD physical-layer transceiver with on-chip power management - typically one or more low-dropout (LDO) regulators - and optional watchdog, SPI control and wake-up logic. In the automotive ECU hierarchy, an SBC sits between the 12 V board net, the host microcontroller, and the CAN bus, replacing several discrete components: an HS-CAN transceiver, a 5 V or 3.3 V regulator for the MCU, reverse-battery protection and bus ESD protection. The wider taxonomy is: SBC -> CAN transceiver -> automotive networking IC -> power management IC -> semiconductor.
Key features of the UJA1169ATK/3Z include 250 mA continuous V1 current to power a small MCU, support for CAN FD at 5 Mbit/s, integrated bus dominant clamping and very low-current standby modes with remote wake-up via the bus. The transceiver meets the stringent automotive EMC and ESD requirements of the ISO 11898-2:2016 standard and the SAE J2284-1 to J2284-5 specifications, while the integrated regulator and protection circuitry reduce external component count and PCB area in ECU designs.
Architecturally, the part uses a high-voltage analog/mixed-signal process for the bus-side drivers and a low-voltage digital block for the SPI register set and V1 LDO. This dual-rail approach allows direct connection to a 12 V automotive supply while still powering the host MCU from the on-chip 3.3 V regulator in the /3Z variant.
Typical applications include body control modules, gateway ECUs, CAN node power management in 12 V systems, ADAS sensor interface nodes and any automotive system that needs a single-chip CAN interface plus local MCU supply. Compared with discrete CAN transceivers plus external regulators, the UJA116ATK family shrinks the BOM and simplifies EMC compliance.
When designing with the UJA1169ATK/3Z, ensure the 12 V supply is properly filtered, route the CANH/CANL lines as a 120 ohm twisted pair, and decouple V1 with the value recommended in the manufacturer datasheet. The /3Z variant is the 3.3 V V1, tape-and-reel orderable variant; the 5 V variant is the UJA1169ATK/F/3Z and the non-Z variants differ only in packing or V1 voltage.

Ứng dụng tiêu biểu
UJA1169ATK/3Z phù hợp cho 6 Áp dụngs: Automotive Body Control Module (BCM), CAN Gateway ECU Node, ADAS Sensor Interface Node, Industrial CAN Node / PLC Module, Electric Vehicle Charging Equipment (EVSE) Communication, CAN-Enabled IoT and Smart Sensor Edge Nodes.
Automotive Body Control Module (BCM)
The UJA1169ATK/3Z is well suited for body control modules because it combines a 5 Mbit/s CAN FD transceiver with an integrated 3.3 V/250 mA LDO that powers the host MCU without a separate regulator. In a BCM, the SBC is wired directly to the 12 V board net, the CANH/CANL pins connect to the chassis CAN bus, and V1 supplies the BCM microcontroller. Compared with a discrete HS-CAN transceiver plus an external LDO, the UJA1169ATK/3Z reduces BOM count, saves PCB area, and inherits AEC-Q100 Grade 1 (-40C to +125C) qualification. The integrated bus fault protection simplifies ISO 11898-2:2016 EMC compliance.

CAN Gateway ECU Node
In a CAN-to-CAN gateway, the UJA1169ATK/3Z serves as the on-board CAN interface for a small node MCU that handles message routing or diagnostics. The integrated 3.3 V V1 LDO eliminates the need for a separate regulator, while CAN FD support at 5 Mbit/s enables the gateway to bridge between classic CAN and CAN FD segments. The HVSON-20 (3.5 x 5.5 mm) package is well matched to space-constrained gateway PCBs, and AEC-Q100 qualification allows the same design to be reused across automotive tiers.

ADAS Sensor Interface Node
ADAS sensor nodes (radar, lidar, camera peripherals) typically communicate over CAN FD to a central ECU, and the UJA1169ATK/3Z provides the physical-layer interface plus local MCU power. Its 250 mA V1 regulator easily handles small sensor MCUs, while ISO 11898-2:2016 compliance guarantees interoperability with downstream ADAS ECUs. The AEC-Q100 Grade 1 rating supports under-hood or behind-bumper mounting where ambient temperatures reach +125C. Using the UJA1169ATK/3Z reduces the node BOM and shortens EMC qualification cycles.

Industrial CAN Node / PLC Module
Outside automotive, the UJA1169ATK/3Z is an excellent fit for industrial CAN nodes, PLC I/O modules and factory-automation peripherals that need a compact, robust HS-CAN interface. The integrated 3.3 V/250 mA LDO supplies the host MCU, the wide operating temperature range tolerates factory-floor environments, and CAN FD support enables high-throughput diagnostics. Compared with industrial-only CAN transceivers, the SBC form factor simplifies layout and improves ESD/bus-fault robustness. Source: NXP UJA1169ATK product page.

Electric Vehicle Charging Equipment (EVSE) Communication
EV charging stations communicate with the vehicle ECU over CAN, and the UJA1169ATK/3Z provides a single-chip interface plus MCU supply for the EVSE controller board. CAN FD support at 5 Mbit/s future-proofs the design for higher-bandwidth charge-status messaging, while AEC-Q100 qualification is overkill but not problematic for the harsher thermal environment of outdoor charging cabinets. The HVSON-20 package allows compact charger PCB layouts. Source: NXP UJA1169ATK family datasheet.

CAN-Enabled IoT and Smart Sensor Edge Nodes
Industrial IoT gateways and edge sensors often use CAN as a robust, differential, long-cable physical layer for factory or building-automation networks. The UJA1169ATK/3Z gives an IoT node MCU a CAN interface plus a 3.3 V supply, with the AEC-Q100 rating offering extra headroom for harsh-edge environments. CAN FD at 5 Mbit/s supports higher telemetry payloads than classic CAN. Compared with USB or RS-485 based IoT nodes, a CAN edge node using the UJA1169ATK/3Z benefits from the multi-drop bus topology and strong EMC immunity of CAN.

Ghi chú thiết kế
The UJA1169ATK/3Z internal V1 LDO supplies 250 mA at 3.3 V to the host MCU. Decouple V1 with a low-ESR ceramic capacitor (typically 1-10 uF X7R) placed within 5 mm of the V1 pin, and bulk-decouple the BAT pin per the manufacturer datasheet. Estimated: at 250 mA full load, internal dissipation in the LDO is (VIN-3.3 V) x 0.25 A - keep VIN as close to 3.3 V as possible at low input voltages to minimise thermal stress.
Route the CANH and CANL traces as a 100 ohm differential pair (120 ohm CAN-typical) with matched length, and keep them away from switching nodes and noisy digital traces. The exposed thermal pad of the HVSON-20 package must be soldered to a continuous PCB ground pour with multiple thermal vias to the inner ground plane - this both grounds the die and provides the primary heat-dissipation path. Maintain 4-wire Kelvin routing from V1 sense to the MCU to avoid IR-drop on the supply rail.
Do not confuse the /3Z suffix (3.3 V V1, tape-and-reel) with the /F/3Z (5 V V1 with /F features). The standard UJA1169ATK and UJA1169ATK/F use 5 V V1; only the /3 variants use 3.3 V V1. Choosing the wrong V1 voltage can permanently damage a 3.3 V-only MCU. The 'Z' suffix indicates Reel 13" packing in a Sulfur Barrier Bag - per NXP community, the /X/F and /X/FZ are the same die with different orderable packing codes.
Estimated: at VIN = 12 V and V1 = 3.3 V delivering 250 mA, the internal LDO dissipates (12 - 3.3) x 0.25 = 2.175 W. The HVSON-20 package's theta_JA is typically around 40-50 C/W on a standard 2-layer JEDEC PCB, leading to a junction temperature rise of 87-109 C above ambient. Derate V1 current in high-ambient-temperature environments, or add thermal vias and copper pours under the exposed pad to lower theta_JA.
