MCP2050T-500E/SL

Drivers, Receivers, Transceivers Overview

The MCP2050T-500E/SL is a LIN transceiver with an integrated 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 within a supply voltage range of 6.0V to 18.0V. The device features a 5.0V LDO output with 70 mA capability and ±3% tolerance over the -40°C to +125°C temperature range. It includes a programmable windowed watchdog timer (WWDT) adjustable from 7 ms to 140 ms via an external resistor. Key electrical protections include 43V load dump tolerance, 30V continuous input voltage, and high EMI immunity.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 5.0V low-dropout voltage regulator providing up to 70 mA for microcontroller power supply
• Programmable windowed watchdog timer allowing system reset window adjustment via external resistor
• Ratiometric VBAT output pin scaled to VREG for analog-to-digital converter monitoring
• Robust automotive-grade protection against load dump, reverse battery, and short circuits

Drivers, Receivers, Transceivers Applications

• Automotive body control modules requiring LIN communication
• Industrial applications needing isolated half-duplex serial bus interfaces
• Systems utilizing PIC microcontrollers with EUSART or standard USARTs

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'T' indicates tape-and-reel packaging rather than tube packaging. Confirm the '-500' designation corresponds to the 5.0V regulator variant. Ensure the 'E' suffix meets RoHS compliance requirements. Cross-reference the specific datasheet revision DS20002299C for accurate pinout and electrical characteristics before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5.0V regulated supply is required alongside LIN transceivers. Choose the SOIC-14 package for surface mount assembly. Verify that the external WWDT resistor value falls within the 33 kΩ to 680 kΩ range to achieve desired timing windows. Ensure the application environment stays within the specified -40°C to +125°C operating temperature limits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MCP2050 family, which also includes variants with 3.3V regulators and different package options like QFN. The 'T' suffix specifically denotes reel packaging for automated assembly. The device serves as a physical layer interface translating CMOS/TTL logic levels to LIN bus standards for reliable automotive data transmission.
