MCP2022P-330E/SL

Drivers, Receivers, Transceivers Overview

The MCP2022P-330E/SL is a Local Interconnect Network (LIN) transceiver compliant with LIN Bus Specifications 1.3, 2.1 and SAE J2602-2. It supports baud rates up to 20 kBaud and operates within a supply voltage range of 6.0V to 18.0V continuous, with a maximum input voltage of 30V. The device features an integrated 3.3V voltage regulator capable of delivering 50 mA, protected against short circuits and thermal overload. It includes automatic thermal shutdown and wake-up functionality triggered by the falling edge of the LBUS voltage. Operating temperatures range from -40°C to +125°C, and it is housed in an 8-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 3.3V voltage regulator with 50 mA output capability
• Wake-up on falling edge of LBUS voltage for improved state control
• Switchable internal pull-up resistor to reduce system current consumption
• Protection against load dump transients up to 43V

Drivers, Receivers, Transceivers Applications

• Automotive LIN bus physical layer interface
• Industrial serial network communication nodes
• Microcontroller interfaces requiring low-power standby modes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'SL' corresponds to the 8-pin SOIC package configuration as documented in the manufacturer's datasheet. Confirm that the component meets RoHS compliance requirements for the intended application environment. Ensure the design accounts for the required external filter capacitors to maintain regulator stability under varying temperature conditions.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when a falling-edge sensitive wake-up mechanism is required rather than level-sensitive detection. The switchable pull-up resistor feature allows for reduced quiescent current in fault states compared to non-P variants. Ensure the microcontroller interface supports the open-drain FAULT/TXE pin logic levels and provides necessary pull-up resistance if not present internally.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2021/2/1P/2P family of LIN transceivers manufactured by Microchip Technology. The 'P' designation indicates enhanced power management features including switchable pull-ups and edge-triggered wake-up. The '330' suffix specifies the 3.3V regulator output option, distinguishing it from the 5.0V regulated versions within the same package lineup.

Drivers, Receivers, Transceivers Replacement Considerations

MCP2022-330E/SL serves as a functional alternative but lacks the switchable pull-up and edge-triggered wake-up features. MCP2022P-500E/SL offers identical control logic but provides a 5.0V regulator output instead of 3.3V. Verify package compatibility and regulator voltage requirements before substitution.
