MTD6502B-LC1-02

Overview

The MTD6502B-LC1-02 is a highly integrated, 3-phase sensorless brushless DC motor controller designed for low-voltage applications. It operates on a 5V supply and supports sinusoidal commutation for smooth motor control. The device features an operating supply current of 50 uA and delivers an output current capability of 500 mA. It is housed in a compact 10-pin TDFN (3x3) package with an exposed pad, suitable for space-constrained designs. The component functions within a temperature range of -40°C to +95°C, ensuring reliability in various environmental conditions.

Feature Summary

• Sensorless sinusoidal commutation for 3-phase BLDC motors
• Highly integrated design reducing external component count
• Low standby current consumption for energy efficiency
• Compact 10-pin TDFN package for small form factors

Applications

• Brushless DC fan controllers
• Small appliance motor drives
• HVAC system fans

Procurement Notes

Verify the exact part number suffix LC1-02 against the manufacturer's official datasheet to confirm packaging media and tape-and-reel specifications. Ensure that the ordering information matches the required temperature grade and package variant. Cross-reference the RoHS compliance status and country of origin if specific regulatory requirements apply to your manufacturing process.

Selection Notes

Select this component when a 5V single-supply solution is required for sensorless 3-phase BLDC fan control. Consider the 500 mA output current limit and the TDFN thermal performance for your specific load requirements. Evaluate the need for sinusoidal drive characteristics versus trapezoidal alternatives based on noise and vibration constraints in the target application environment.
