MCP8025T-115E/MP

Overview

The MCP8025T-115E/MP is a three-phase brushless DC motor gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 6 V to 19 V and supports output currents up to 30 mA. The device features a low operating supply current of 1.15 mA and functions reliably across an extended temperature range from -40 °C to +150 °C. It is housed in a TQFP-EP-48 surface-mount package, designed for robust integration into motor control applications requiring linear drive characteristics.

Feature Summary

• Provides dedicated gate driving capabilities for three-phase brushless DC motors
• Supports linear drive topology for precise motor control applications
• Operates with low quiescent current consumption for energy efficiency

Applications

• Three-phase BLDC motor control systems
• Industrial motion control drives
• Automotive ignition and power management circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '115E' designation aligns with the required electrical specifications and temperature grade. Ensure the TQFP-EP-48 footprint matches your PCB layout requirements. Cross-reference the manufacturer datasheet for any recent errata or design changes affecting this specific part number before finalizing procurement.

Selection Notes

Select this component when a linear gate driver architecture is preferred over high-side/low-side bridge drivers for specific BLDC applications. Consider the 30 mA output capability against the gate charge requirements of the external MOSFETs. Evaluate the 1.15 mA supply current against system power budgets. Verify that the 6 V to 19 V input range covers the available bus voltage in the target application environment.

Part Context

This component belongs to the MCP8025 family of motor controllers from Microchip Technology. It is distinct from higher-current variants like the MCP8025AT which offer 500 mA outputs and different packaging. The standard MCP8025 series focuses on lower-power linear drive solutions suitable for smaller motors or specific control topologies where simplicity and linearity are prioritized over maximum switching speed.

Replacement Considerations

Direct substitutes include other MCP8025 variants such as MCP8025-115E/PT, differing primarily in packaging format. Higher performance replacements may involve the MCP8025AT series for increased current drive. Always verify pin compatibility and thermal requirements when substituting.
