MCP2025-500E/SN

The MCP2025-500E/SN is a LIN Transceiver with voltage regulator. It provides a bidirectional, half-duplex communication physical interface to meet the LIN bus specification Revision 2.1 and SAE J2602-2. The device incorporates a voltage regulator with 5 or 3.3V 70mA regulated power supply output. The device has been designed to meet the stringent quiescent current requirements of the automotive industry and will survive 43V load dump transients and double battery jumps. It provides a physical interface between a microcontroller and a LIN half-duplex bus. It is intended for automotive and industrial applications with serial bus baud rates up to 20kbaud. This device will translate the CMOS/TTL logic levels to LIN logic levels and vice versa. The device offers optimum EMI and ESD performance; it can withstand high voltage on the LIN bus. The device supports two low-power modes to meet automotive industry power consumption requirements.

• Interface to PIC® EUSART and standard USARTs
• Wake-up on LIN Bus activity or local wake input Internal pull-up termination resistor and diode
• Protected against VBAT shorts
• Protected against loss of ground
• High current drive
• TXD and LIN Bus dominant time-out function
• Internal short circuit current limit
• Only external filter and load capacitors needed
• Automatic thermal shutdown protection
• Transient protection for LBUS and VBB pins in automotive environment (ISO7637)
• Compliant with SAE J2602-2
• 43V load dump protected
