MCP8025AT-115H/PT

Overview

The MCP8025AT-115H/PT is a 3-phase brushless DC motor gate driver and power module manufactured by Microchip Technology. It integrates a LIN transceiver and features a Key Off Sleep mode for enhanced power management. The device operates within a supply voltage range of 6 V to 19 V and supports an output current of 30 mA. It is housed in a 48-lead TQFP package with an exposed pad (TQFP-EP-48) and is rated for operation between -40°C and +150°C.

Feature Summary

• Integrates a LIN transceiver for local interconnect network communication
• Features Key Off Sleep mode to minimize power consumption during standby
• Designed as a complete 3-phase BLDC motor gate driver and power module

Applications

• 3-phase brushless DC motor control systems
• Automotive ignition and motion control applications
• Industrial motor drives requiring LIN bus connectivity

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's latest documentation, as it may denote automotive grade or specific temperature variants distinct from standard commercial parts. Confirm the tape and reel packaging quantity matches project requirements. Ensure the 48-lead TQFP footprint aligns with PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a combined gate driver and LIN transceiver solution is required for 3-phase BLDC motors. The integrated power module simplifies design compared to discrete solutions. Consider the 30 mA output capability and 6-19 V operating range to ensure compatibility with the target motor load and system voltage architecture.

Part Context

This part belongs to the MCP8025 family of motor drivers. It shares functional similarities with models like the MCP8025-115E/PT but differs in packaging and potentially qualification grades. The 'AT' suffix typically indicates automotive temperature rating and tape/reel packaging, while 'H' often denotes specific automotive reliability standards.

Replacement Considerations

Direct substitutes include other MCP8025 variants such as MCP8025AT-115E/PT or MCP8025A-115H/PT, provided pinout and electrical specifications match. Verify that alternative packages (e.g., QFN vs. TQFP) are compatible with existing board layouts.
