Microchip High Speed CAN Bus Transceiver, LIN, 4.5V to 5.5V, SOIC

This Microchip High Speed CAN Bus Transceiver serves as a reliable interface between a CAN protocol controller and the physical two-wire CAN bus. Designed to meet stringent automotive requirements, it offers high-speed data transmission up to 1Mbps, low quiescent current, and excellent electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection.

Fully compatible with ISO-11898-2 and ISO-11898-5 standards, the device provides differential transmit and receive capability. A key advantage is that CAN bus pins are disconnected when the device is unpowered, ensuring an unpowered node or brown-out event will not load the CAN bus.

Advanced Protection and Features

• Very low standby current (typically 5µA)
• VIO supply pin to interface directly with CAN controllers and microcontrollers
• Detection of ground faults
• Permanent dominant detection on TXD and the bus
• Power-on reset and voltage brown-out protection on VDD and VIO pins
• Protection against short-circuit conditions (positive or negative battery voltage)
• Protection against high-voltage transients in automotive environments
• Automatic thermal shutdown protection
• High-noise immunity due to differential bus implementation
• Supports up to 112 connected nodes

Product Dimensions and Handling

The component is housed in an SOIC package and features compact dimensions of 43 mm in height, 33 mm in width, and 15 mm in depth, with a lightweight design of just 0.454 grams. Please note: This is an ESD sensitive device, so proper handling precautions must be taken.
