MCP2025-330E/SN

Drivers, Receivers, Transceivers Overview

The MCP2025-330E/SN is an 8-pin SOIC LIN transceiver with a 3.3V voltage regulator, compliant with LIN Bus Specifications Version 1.3, 2.1 and SAE J2602-2. It supports baud rates up to 20 kBaud and operates on a wide supply voltage range of 6.0V to 18.0V. The device withstands 43V load dump transients and features a maximum continuous input voltage of 30V. It includes two low-power modes: Transmitter Off at 90 µA typical and Power Down at 4.5 µA typical. The integrated LDO provides a regulated 3.3V output at 70 mA capability with ±3% tolerance over the -40°C to +125°C extended temperature range.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 3.3V Low Dropout Regulator (LDO) providing up to 70 mA output current for microcontroller power supply.
• Robust automotive-grade protection including 43V load dump tolerance, ISO 7637 transient protection, and ±15 kV ESD immunity on LBUS and VBB pins.
• Dual low-power operational modes designed to minimize quiescent current consumption in standby states.
• Built-in fail-safe mechanisms including automatic thermal shutdown, short-circuit current limiting, and TXD/LBUS dominant time-out function.

Drivers, Receivers, Transceivers Applications

• Automotive Local Interconnect Network (LIN) bus physical layer interfaces
• Microcontroller-to-LIN half-duplex communication bridges
• Industrial applications requiring serial bus connectivity up to 20 kBaud

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type and regulatory compliance standards. Confirm the internal voltage regulator output aligns with the target microcontroller's supply requirements. Ensure external component selection, particularly filter capacitors, meets stability criteria defined in the datasheet electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when a fixed 3.3V regulated supply is needed alongside LIN communication. Compare against the MCP2025-500 if a 5.0V regulator output is preferred. Evaluate the need for the exposed thermal pad or alternative packages based on PCB layout constraints and thermal dissipation requirements in the final assembly.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2025 family of LIN transceivers manufactured by Microchip Technology. The family differentiates primarily by the internal voltage regulator output voltage, offering both 5.0V and 3.3V options. It serves as a physical interface solution for automotive and industrial networks requiring robust fault protection and low power consumption.
