MCP2021A/2A  
LIN Transceiver with Voltage Regulator  
Features:  
Description:  
• The MCP2021A/2A are compliant with LIN Bus  
Specifications Version 1.3, 2.1 and with SAE  
J2602-2  
The MCP2021A/2A provide a bidirectional, half-duplex  
communication physical interface to meet the LIN bus  
specification Revision 2.1 and SAE J2602-2. The  
devices incorporate a voltage regulator with 5V or 3.3V  
at 70 mA regulated power supply output. The devices  
have been designed to meet the stringent quiescent  
current requirements of the automotive industry and  
will survive +43V load dump transients and double  
battery jumps.  
• Support Baud Rates up to 20 kBaud  
• 43V Load Dump Protected  
• Maximum Continuous Input Voltage: 30V  
• Wide LIN-Compliant Supply Voltage: 6.0 – 18.0V  
• Extended Temperature Range: -40 to +125°C  
• Interface to PIC® MCU EUSART and Standard  
USARTs  
Package Types  
• Wake-Up on LIN Bus Activity or Local Wake Input  
• Local Interconnect Network (LIN) Bus Pin:
