MCP8025AT-115H/MPVAO

Overview

The MCP8025AT-115H/MPVAO is a three-phase brushless DC motor gate driver featuring an integrated key-off mode for enhanced power management. It operates within a supply voltage range of 6 V to 19 V and supports adjustable output voltages. The device delivers an output current of 500 mA with a quiescent operating current of 200 µA. Designed for automotive-grade reliability, it functions across an extended temperature range from -40°C to +150°C. The component is housed in a QFN-40 surface-mount package.

Feature Summary

• Integrates a dedicated key-off mode to minimize power consumption when the system is inactive.
• Provides high-efficiency driving capabilities for precise control of BLDC motor speed and torque.
• Supports adjustable output voltage configurations to accommodate various motor requirements.

Applications

• Precision control of brushless DC motors in automotive systems
• High-efficiency motor drive solutions requiring low standby power
• Automotive motion control applications operating in extreme temperatures

Procurement Notes

Verify the specific suffix 'VAO' indicates automotive qualification and lead-free compliance as per Microchip documentation. Confirm the QFN-40 package type matches your PCB footprint design. Ensure the 500 mA output current rating aligns with your motor load requirements. Cross-reference the datasheet for any errata or specific ordering information related to the MPVAO variant.

Selection Notes

Select this component for applications requiring robust automotive-grade performance and low quiescent current. The 500 mA output capability suits moderate-power BLDC motors. Consider the QFN-40 package for compact designs. Verify thermal dissipation needs given the 150°C maximum junction temperature rating. Compare against standard MCP8025 variants if automotive certification is not required.
