描述 Description

The UJA1161ATK is a ‘self-supplied’ high-speed CAN transceiver with Standby mode integrating an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant HS-CAN transceiver and an internal 5 V CAN supply. The only supply input is a battery connection. The UJA1161ATK can be operated in a very-low-current Standby mode with bus wake-up capability.
This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.
