MCP2022T-330E/SL

Drivers, Receivers, Transceivers Overview

The MCP2022T-330E/SL is a LIN transceiver with an integrated 3.3V voltage regulator, designed for automotive and industrial applications. It supports LIN Bus Specifications 1.3, 2.1, and SAE J2602-2 at baud rates up to 20 kBaud. The device operates within a wide supply voltage range of 6.0V to 18.0V continuous, with a maximum input of 30V. It features extended temperature operation from -40°C to +125°C and includes two low-power modes: Receiver On (approx. 85 µA) and Receiver Monitoring (approx. 16 µA). The package is SOIC-14.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 3.3V LDO voltage regulator with short-circuit protection and thermal shutdown
• Compliant with LIN Bus Specifications 1.3, 2.1 and SAE J2602-2 standards
• Supports remote wake-up via CS/LWAKE pin or LIN bus activity
• Includes RESET output pin for system monitoring

Drivers, Receivers, Transceivers Applications

• Automotive Local Interconnect Network (LIN) systems
• Industrial serial bus networks
• Microcontroller interface to half-duplex LIN buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the '330' designation corresponds to the 3.3V regulator variant. Ensure the 'SL' suffix matches the required SOIC-14 package type. Check for any RoHS compliance documentation updates. Validate that the component meets current automotive qualification requirements for the intended application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a 3.3V regulated supply is required for the connected microcontroller. Choose the MCP2022 over MCP2021 variants if a dedicated RESET output pin is necessary for system supervision. Consider the TSSOP or PDIP packages if surface mount density is not the primary constraint. Verify that the 20 kBaud speed requirement aligns with the network design specifications.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2021/2/1P/2P family of LIN transceivers manufactured by Microchip Technology. The MCP2022 variant specifically adds a RESET output pin compared to the base MCP2021. The '330' suffix denotes the 3.3V regulator option, while '500' would indicate a 5.0V regulator. The 'T' suffix typically signifies tape and reel packaging.
