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 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

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
