MCP2021/2/1P/2P  
LIN Transceiver with Voltage Regulator  
Features:  
Description:  
• The MCP2021/2/1P/2P are Compliant with LIN  
Bus Specifications 1.3, 2.1 and are Compliant to  
SAE J2602-2  
The MCP2021/2/1P/2P provides a bidirectional, half-  
duplex communication physical interface to automotive  
and industrial LIN systems that meets the LIN bus  
specification Revision 2.1 and SAE J2602-2. The  
devices incorporate a voltage regulator with 5V at  
50 mA or 3.3V at 50 mA regulated power-supply  
outputs.  
• Support Baud Rates up to 20 kBaudwith  
LIN-compatible Output Driver  
• 43V Load Dump Protected  
• Very Low EMI Meets Stringent OEM Requirements  
• Wide Supply Voltage, 6.0V-18.0V Continuous:  
- Maximum input voltage of 30V  
The regulator is short-circuit protected, and is protected  
by an internal thermal shutdown circuit. The device has  
been specifically designed to operate in the automotive  
operating environment and will survive all specified  
transient conditions while meeting all of the stringent  
quiescent current requirements.  
• Extended Temperature Range: -40 to +125°C  
• Interface to PIC® EUSART and Standard USARTs  
• Local Interconnect Network (LIN) Bus Pin:  
- Internal pull-up resistor and diode  
- Protected against ground shorts  
The MCP2021/2/1P/2P family of devices includes the  
following packages.  
- Protected against loss of ground  
- High-current drive  
8-pin PDIP, DFN and SOIC packages:  
• MCP2021-330, LIN-compatible driver, 8-pin, 3.3V  
regulator, wake up on dominant level of LBUS  
• Automatic Thermal Shutdown  
• On-Chip Voltage Regulator:  
• MCP2021-500, LIN-compatible driver, 8-pin, 5.0V  
regulator, wake up on dominant level of LBUS  
- Output voltage of 5.0V with tolerances of  
±3% overtemperature range  
• MCP2021P-330, LIN-compatible driver, 8-pin,  
3.3V regulator, wake up at falling edge of LBUS  
voltage  
- Available with alternate output voltage of  
3.3V with tolerances of ±3% overtemperature  
range  
• MCP2021P-500, LIN-compatible driver, 8-pin,  
5.0V regulator, wake up at falling edge of LBUS  
voltage  
- Maximum continuous input voltage of 30V  
- Internal thermal overload protection  
- Internal short circuit current limit  
14-pin PDIP, TSSOP and SOIC packages with RESET  
output:  
- External components limited to filter capacitor  
and load capacitor  
• MCP2022-330, LIN-compatible driver, 14-pin,  
3.3V regulator, RESET output, wake up on  
dominant level of LBUS  
• Two Low-Power modes:  
- Receiver On, Transmitter Off, Voltage  
• MCP2022-500, LIN-compatible driver, 14-pin,  
5.0V regulator, RESET output, wake up on  
dominant level of LBUS  
Regulator On (85 µA)  
- Receiver Monitoring Bus, Transmitter Off,  
Voltage Regulator Off (16 µA)  
• MCP2022P-330, LIN-compatible driver, 14-pin,  
3.3V regulator, RESET output, wake up at falling  
edge of LBUS voltage  
• MCP2022P-500, LIN-compatible driver, 14-pin,  
5.0V regulator, RESET output, wake up at falling  
edge of LBUS voltage
