MCP2022-330E/ST

Drivers, Receivers, Transceivers Overview

The MCP2022-330E/ST is a LIN transceiver providing a bidirectional, half-duplex physical interface for automotive and industrial Local Interconnect Network (LIN) systems. It complies with LIN Bus Specifications 1.3, 2.1, and SAE J2602-2, supporting baud rates up to 20 kBaud. The device features an integrated 3.3V voltage regulator capable of delivering 50 mA with ±3% tolerance over the operating temperature range. It operates on a wide supply voltage from 6.0V to 18.0V continuous, with a maximum input of 30V. The component includes thermal shutdown, short-circuit protection, and wake-up capabilities via the CS/LWAKE pin or LIN bus activity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the selected variant matches the required regulator output voltage and pin configuration for your PCB layout. Cross-reference the part number with official Microchip documentation to validate availability and revision history before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3V regulated output is required for the connected microcontroller or peripheral devices within the LIN network. Choose this part over the 5.0V variant if the system logic operates at 3.3V. Consider the 14-pin package requirements for the additional RESET and NC pins compared to the 8-pin versions. Ensure the application environment stays within the specified -40°C to +125°C extended temperature range.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MCP2021/2/1P/2P family of LIN transceivers manufactured by Microchip Technology. The MCP2022 variant specifically distinguishes itself by offering a 14-pin package that includes a dedicated RESET output pin for monitoring regulator health. It serves as the physical layer interface between CMOS/TTL logic microcontrollers and the LIN bus, translating signal levels while providing necessary power regulation and fault protection.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other members of the MCP2021/2/1P/2P family such as the MCP2022-500E/ST for 5.0V regulator applications. Verify pin compatibility and regulator voltage specifications when considering alternative packages like PDIP or SOIC variants within the same series.
