概述

The TPT1043AQ is a CAN transceiver that meets the ISO11898-2:2024, SAEJ2284-1 to SAE J2284-5 highspeed CAN (Controller Area Network) physical layer standard.

The devices are designed to be used in CAN FD networks up to 5 Mbps with enhanced timing margin and higher data rates in long and highly loaded networks, and support up to 8-Mbps data rates in simple CAN bus networks. The system design can be optimized with excellent electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance. The TPT1043AQ has a secondary power supply input VIO pin for I/O level shifting to support 1.8-V, 2.5-V, 3.3-V, and 5-V MCU logic levels directly. The device has low-current standby and sleep mode with CAN bus wake-up capability via wake-up pattern (WUP) which is defined in ISO11898-2:2024. The device supports ultra-low power management to power down the entire node and enables the power supply by the INH pin through the local or remote wake-up with wake-up source recognition capability.

As designed, the devices feature bus fault protection from −45 V to +45 V, TXD dominant time-out (DTO), and over-temperature shutdown (TSD). Additionally, all devices include power-off ideal passive behavior fail-safe features to enhance the network robustness.

The TPT1043AQ is available in SOP14 and DFN4.5X3-14 packages and is AEC-Q100 qualified for automotive applications.
