MCP2022T-500E/SL

Drivers, Receivers, Transceivers Overview

The MCP2022T-500E/SL is a LIN transceiver with an integrated 5.0V LDO voltage regulator, designed for automotive and industrial applications. It supports baud rates up to 20 kBaud and complies with LIN Bus Specifications 1.3, 2.1, and SAE J2602-2. The device operates on a supply voltage of 6.0V to 18.0V continuous, with a maximum input voltage of 30V. It features two low-power modes: Receiver On (approx. 85 µA) and Receiver Monitoring (approx. 16 µA). The regulator provides 5.0V at 50 mA with ±3% tolerance over the -40°C to +125°C temperature range. It includes thermal shutdown, short-circuit protection, and wake-up capabilities via CS/LWAKE or LIN bus activity.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 5.0V voltage regulator with short-circuit and thermal overload protection
• Supports LIN Bus Specifications 1.3, 2.1 and SAE J2602-2 compliance
• Low-power operation with distinct receiver-on and monitoring modes
• Robust transient protection including 43V load dump survival

Drivers, Receivers, Transceivers Applications

• Automotive Local Interconnect Network (LIN) systems
• Industrial serial bus networks requiring half-duplex communication
• Microcontroller interfaces for LIN master and slave nodes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' against official documentation, as standard listings often use 'ST' for TSSOP or 'SL' for SOIC. Confirm package type matches design requirements. Check datasheet revision history for any functional updates. Ensure ordering codes align with Microchip's current naming conventions to avoid procurement errors.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5.0V regulated supply is needed alongside LIN communication. Compare with MCP2022-330 if a 3.3V output is required. Consider the MCP2021 family if a RESET pin is not necessary. Evaluate power consumption needs against the available low-power modes. Verify compatibility with microcontroller UART interfaces.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MCP2021/2/1P/2P family of LIN transceivers. It shares core functionality with the MCP2022 series but differs in package and specific control logic variations found in the 'P' variants. The '500' designation indicates the 5.0V regulator option. It serves as a physical layer interface between CMOS/TTL logic and the LIN bus.

Drivers, Receivers, Transceivers Replacement Considerations

MCP2022-500E/ST is a direct alternative with identical electrical characteristics but in a TSSOP package. MCP2022-500E/SL offers the same function in an SOIC package. For 3.3V regulation, consider the MCP2022-330 series. Verify pinout compatibility before substitution.
