MCP2562-H/MF

Drivers, Receivers, Transceivers Overview

The MCP2562-H/MF is a high-speed CAN transceiver from Microchip Technology, designed for automotive and industrial applications. It supports data rates up to 1 Mb/s and complies with ISO-11898-2 and ISO-11898-5 standards. The device operates within a supply voltage range of 4.5 V to 5.5 V on the VDD pin and 1.8 V to 5.5 V on the VIO pin. It features an operating temperature range of -40°C to +150°C (High grade). Key electrical characteristics include a typical standby current of 5 µA, ESD protection up to ±14 kV on CANH/CANL, and thermal shutdown at approximately 175°C. The component is housed in an 8-lead DFN package.

Drivers, Receivers, Transceivers Feature Summary

• Features a dedicated VIO supply pin that allows direct interfacing with microcontrollers having digital I/O levels ranging from 1.8 V to 5.5 V without external level shifters.
• Provides robust protection against short-circuit conditions, including positive and negative battery voltage faults, as well as high-voltage transients common in automotive environments.
• Includes permanent dominant detection logic that disables output drivers if a stuck-low condition is detected on the TXD input or the bus, preventing bus corruption.
• Supports low-power Standby mode with wake-up functionality, enabling the device to monitor the bus for activity while minimizing power consumption.

Drivers, Receivers, Transceivers Applications

• Automotive electronic control units (ECUs) requiring high-temperature operation
• Industrial communication networks utilizing CAN protocols
• Systems integrating 1.8 V or 3.3 V microcontrollers with CAN buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffixes to ensure the correct package type and temperature grade are selected. Confirm that the VIO pin connection matches the target microcontroller's I/O voltage requirements. Check datasheet specifications for absolute maximum ratings to prevent damage during installation.

Drivers, Receivers, Transceivers Selection Notes

Select this model over the MCP2561 when the application requires a separate VIO supply pin for flexible digital I/O voltage levels rather than a SPLIT pin for common-mode stabilization. Ensure the system design accommodates the 3x3 mm DFN package footprint and thermal pad requirements for adequate heat dissipation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2561/2 family of high-speed CAN transceivers. The MCP2562 variant is distinguished by its VIO pin, whereas the MCP2561 includes a SPLIT pin for biased split termination schemes. Both devices share similar fault protection and operational modes but differ in their digital interface configurations.
