MCP2562-E/MF Microchip

MCP2561/2 High-Speed CAN Transceiver Features: Description: Supports 1 Mb/s Operation The MCP2561/2 is a Microchip Technology Inc. second generation high-speed CAN transceiver. It serves as an Implements ISO-11898-2 and ISO-11898-5 interface between a CAN protocol controller and the Standard Physical Layer Requirements physical two-wire CAN bus. Very Low Standby Current (5 A, typical) The device meets the automotive requirements for VIO Supply Pin to Interface Directly to high-speed (up to 1 Mb/s), low quiescent current, CAN Controllers and Microcontrollers with electromagnetic compatibility (EMC) and electrostatic 1.8V to 5.5V I/O discharge (ESD).
