MP6505DM-LF-P

Overview

The MP6505DM-LF-P is a single-phase brushless DC motor driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 4.5V to 16V and delivers an output current of 400mA. The device features an integrated power MOSFET bridge and is housed in a 16-TSSOP package with exposed pad for thermal management. It supports a wide operating temperature range from -40°C to +125°C TJ, ensuring reliability in demanding environments.

Feature Summary

• Integrates a full-bridge power MOSFET stage for direct motor control
• Supports single-phase BLDC motor applications with simplified drive requirements
• Operates over an extended industrial temperature range up to 125°C junction temperature

Applications

• Single-phase brushless DC motor control
• Small appliance fan drives
• HVAC blower motor regulation

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging configuration as per manufacturer standards. Confirm RoHS compliance status through official documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the exact pinout and thermal pad requirements against the official datasheet before PCB layout finalization.

Selection Notes

Select this component for low-voltage single-phase BLDC applications requiring moderate current drive. Compare against the MP6500 series if higher current capacity or stepper motor support is needed. Evaluate thermal performance constraints given the TSSOP-EP package limitations. Ensure input voltage stability remains within the 4.5V to 16V operational window for reliable switching behavior.

Part Context

This part belongs to the MPS motor driver family, designed for compact motion control solutions. It complements higher-power drivers like the MP6500AGF by offering a smaller form factor for lower-load scenarios. The DM variant typically denotes a specific tape-and-reel packaging option within the product line.

Replacement Considerations

MP6505DM-LF is the lead-free equivalent without the reel suffix. MP6500AGF-P serves as a higher-current alternative for different motor types.
