MCP8025T-115E/PT

Overview

The MCP8025T-115E/PT 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 features an output current capability of 30 mA. The device supports a wide operating temperature range from -40 °C to +150 °C, ensuring reliability in demanding environments. It is housed in a TQFP-EP-48 surface-mount package with an exposed pad for enhanced thermal performance. The component draws a typical quiescent supply current of 1.15 mA, making it suitable for applications requiring efficient power management alongside precise motor control capabilities.

Feature Summary

• Integrated three-phase half-bridge gate driver architecture designed specifically for brushless DC motor commutation
• Linear input interface allowing direct connection to microcontroller logic levels without additional level-shifting circuitry
• Extended thermal stability rated for operation up to +150 °C, supporting high-temperature industrial and automotive applications

Applications

• Three-phase brushless DC motor control systems
• Industrial motion control actuators
• Automotive ignition and fuel injection drivers

Procurement Notes

Verify the specific suffix 'T' against the official Microchip datasheet to confirm tape-and-reel packaging designation versus tube variants. Ensure the TQFP-EP-48 footprint matches the target PCB layout, paying close attention to the exposed thermal pad connectivity requirements for proper heat dissipation during operation.

Selection Notes

Select this component when driving low-current BLDC loads directly without external power stages. The 30 mA output limit dictates suitability for small motors or pre-driver stages. Consider the 1.15 mA quiescent current for battery-operated designs where standby power consumption is critical, and verify that the 6 V minimum supply aligns with the system's available rail voltage.

Part Context

This part belongs to the MCP8025 family of motor controllers, which provides integrated solutions for driving three-phase loads. Unlike higher-power variants such as the MCP8025AT series which offer 500 mA outputs in QFN packages, this PT variant focuses on compact surface-mount integration with linear inputs, targeting applications where moderate drive strength and wide temperature tolerance are prioritized over raw current capacity.

Replacement Considerations

The MCP8025-115E/PT serves as a non-taped alternative within the same electrical specification family. Cross-reference pinouts and thermal pad configurations carefully when substituting between tape/reel and tube packaging formats to ensure mechanical compatibility.
