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:

* Includes Exposed Thermal Pad (EP), see Table 1-2.

• 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

1.2, March 2011

• Multiple Package Options, including Small

4x4 mm DFN Package
