概述

The TPT1445Q is a CAN transceiver that meets the ISO11898-2:2024, SAEJ2284-1 to SAE J2284-5, and SAE J1939-14 high-speed CAN (Controller Area Network) physical layer standard.

The devices are designed to be used in CAN FD networks up to 8 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 could be optimized with excellent electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance. The TPT1445Q 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 supports selective wake up and enables the Electronic Control Unit (ECU) to implement the partial networking function which is operating in an active state while it is in a low-power sleep mode. The device comes with the standby mode, which can be waked up from the CAN bus, and ultra-low power management controls the ECU in standby and sleep modes, then enable the power supply by inhibiting output through the local or remote wake-up via wake-up pattern (WUP) or wake-up frame (WUF) which is defined in ISO11898-2:2024.

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

TPT1445Q is available in SOP14 and DFN4.5X3-14 packages and is characterized from –40°C to +125°C.
