MCP8025-115H/PT

Overview

The MCP8025-115H/PT is a 3-phase brushless DC (BLDC) motor gate driver and power module manufactured by Microchip Technology. It operates within a supply voltage range of 6 V to 19 V and is housed in a 48-pin TQFP EP package. The device integrates high-side and low-side drivers for external N-channel MOSFETs, featuring a LIN transceiver interface for configuration and fault reporting. It supports PWM inputs up to 50 kHz and includes a Key-Off Sleep mode for power management.

Feature Summary

• Integrates high-side and low-side drivers for external N-channel MOSFETs
• Includes built-in LIN transceiver for communication and fault signaling
• Features Key-Off Sleep mode for reduced power consumption

Applications

• Three-phase BLDC motor drive systems
• Industrial motion control applications
• Automotive ignition and motor control modules

Procurement Notes

Verify the specific suffix 'H' against official Microchip documentation to confirm pinout and feature variations compared to other MCP8025 variants. Ensure the TQFP-EP-48 package compatibility with your PCB footprint. Confirm that the 6V to 19V operating voltage range aligns with your system's power supply specifications before procurement.

Selection Notes

Select this component when a combined gate driver and LIN interface are required for BLDC motor control. It is suitable for designs needing integrated fault reporting via LIN rather than discrete GPIO monitoring. Consider the 48-pin TQFP EP package for thermal performance and space constraints. Verify that the external MOSFET selection matches the driver's output current capabilities.

Part Context

The MCP8025 series comprises 3-phase BLDC motor gate drivers with integrated power modules. The -115H/PT variant specifically denotes the TQFP-EP-48 packaging and standard temperature grade. This family is designed to simplify motor control designs by integrating driver logic, protection features, and communication interfaces into a single compact solution.

Replacement Considerations

Check Microchip datasheets for alternative suffixes such as /MP or /E which may offer different packaging or temperature ranges. Ensure any substitute maintains the 48-pin TQFP form factor and LIN interface compatibility if software integration is already established.
