MCP2021/2  
LIN Transceiver with Voltage Regulator  
Features  
Description  
• The MCP2021 and MCP2022 are compliant with  
LIN Bus Specifications 1.3, 2.0, and 2.1 and are  
compliant to SAE J2602  
The MCP2021/2 provides a bidirectional, half-duplex  
communication physical interface to automotive, and  
industrial LIN systems to meet the LIN bus specification  
Revision 2.0. The device incorporates a voltage  
regulator with 5V @ 50 mA or 3.3V @ 50 mA regulated  
power supply output. The regulator is short circuit  
protected, and is protected by an internal thermal shut-  
down circuit. The regulator has been specifically  
designed to operate in the automotive environment and  
will survive reverse battery connections, +43V load  
dump transients, and double-battery jumps. The device  
has been designed to meet the stringent quiescent  
current requirements of the automotive industry.  
• Support Baud Rates up to 20 Kbaud with  
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  
• 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  
- Protected against loss of ground  
- High current drive
