1 / 40 page  2012-2014 Microchip Technology Inc. DS20002299C-page 1 MCP2050 Features: • The MCP2050 is compliant with: - LIN Bus Specifications Version 1.3, 2.1 and with SAE J2602-2 • Support Baud Rates Up to 20 kBaud • 43V Load Dump Protected • Maximum Continuous Input Voltage of 30V • Wide LIN Compliant Supply Voltage, 6.0-18.0V • Extended Temperature Range: -40 to +125°C • Interface to PIC® EUSART and Standard USARTs • Wake-Up on LIN Bus Activity or Local Wake Input • LIN Bus Pin - Internal pull-up termination resistor and diode for slave node - Protected against VBAT shorts - Protected against loss of ground - High current drive •TXD and LIN Bus Dominant Time-Out Function • Two Low-Power Modes - Transmitter Off mode: 90 µA (typical) - Power Down mode: 4.5 µA (typical) • Output Indicating Internal Reset State (POR or Sleep Wake) • MCP2050 On-Chip Voltage Regulator - Output voltage of 5.0V or 3.3V with 70 mA capability and tolerances of ±3% over operating temperature range - Internal short-circuit current limit - Only external filter and load capacitors needed • Programmable Windowed Watchdog Timer (WWDT) - External resistor programmable from 7 ms to 140 ms - Disabled by connecting the WWDTSELECT pin to VREG or let the pin float • Ratiometric Output of VBAT Voltage Scaled to VREG • Automatic Thermal Shutdown • High Electromagnetic Immunity (EMI), Low Electromagnetic Emission (EME) • Robust ESD Performance: ±15 kV for LBUS and VBB pin (IEC61000-4-2) • Transient Protection for LBUS and VBB Pins in Automotive Environment (ISO7637) • Meets Stringent Automotive Design Requirements Including “OEM Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications”, Version 1.3, May 2012 • Multiple Package Options Including Small 5x5 QFN Description: The MCP2050 provides a bidirectional, half-duplex communication physical interface to meet the LIN bus specification Revision 2.1 and SAE J2602. The device incorporates a voltage regulator with 5V or 3.3V 70 mA regulated power supply output. The on-chip WWDT allows users to adjust the size of the reset window by using an external resistor. The ratiometric VBAT pin scales down VBAT to the range of VREG so it can be monitored by an A/D converter. 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. MCP2050 family members: - MCP2050-500, 14-pin, LIN driver with 5.0V regulator - MCP2050-330, 14-pin, LIN driver with 3.3V regulator - MCP2050-500, 20-pin QFN, LIN driver with 5.0V regulator - MCP2050-330, 20-pin QFN, LIN driver with 3.3V regulator LIN Transceiver with Voltage Regulator |
