MCP2050T-500E/MQ

Drivers, Receivers, Transceivers Overview

The MCP2050T-500E/MQ is a LIN transceiver with an integrated voltage regulator and programmable windowed watchdog timer. It complies with LIN Bus Specifications Version 1.3, 2.1, and SAE J2602-2, supporting baud rates up to 20 kBaud. The device operates on a supply voltage range of 6.0V to 18.0V and withstands 43V load dump transients. It features a 5.0V output regulator with 70 mA capability and ±3% tolerance over the -40°C to +125°C temperature range. Packaged in a 20-pin 5x5 QFN format, it includes wake-up capabilities, thermal shutdown, and high EMI immunity.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'MQ' corresponds to the 20-pin QFN package variant when sourcing. Confirm that the 'T' designation indicates tape and reel packaging if required by assembly equipment. Ensure the component meets RoHS standards as specified in the datasheet documentation.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring a 5.0V regulated output from the internal LDO. Choose the MQ package variant for space-constrained designs utilizing the 5x5 QFN footprint. Ensure the system design accommodates the external components required for WWDT timing and voltage regulator stability.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2050 family, which includes variants with 3.3V regulators and different package options such as 14-pin SOIC/PDIP. The MCP2050T-500E/MQ specifically denotes the 5.0V regulator version in the small QFN package with tape-and-reel delivery.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements within the same family include the MCP2050-500E/MQ for standard tube packaging or the MCP2050-330 series for 3.3V regulator requirements. Verify pin compatibility and regulator voltage specifications before substitution.
