MTD6502B-LC1-01

Overview

The MTD6502B-LC1-01 is a five-volt, three-phase sensorless brushless DC motor driver designed for fan applications. It operates within a load voltage range of two to five point five volts and supports junction temperatures from minus forty to plus one hundred fifty degrees Celsius. The component utilizes a ten-pin TDFN exposed pad surface-mount package. It integrates sinusoidal commutation control for smooth motor operation without external sensors.

Feature Summary

• Integrates sinusoidal commutation for low-noise BLDC fan control
• Supports sensorless operation eliminating external Hall effect sensors
• Designed for high-temperature environments with extended thermal ratings

Applications

• Computer cooling fans
• Server chassis ventilation systems
• Consumer electronics thermal management

Procurement Notes

Verify the specific suffix LC1-01 against official Microchip documentation to confirm pinout and packaging variations. Ensure compatibility with system voltage rails between two and five point five volts. Confirm thermal requirements align with the specified junction temperature range during integration.

Selection Notes

Select this driver for applications requiring silent, sensorless three-phase BLDC control at five volts. Evaluate thermal dissipation capabilities given the exposed pad package design. Compare performance metrics against alternative drivers if higher voltage or current capacities are required for larger fan loads.

Part Context

This component belongs to the MTD6502B family of motor controllers manufactured by Microchip Technology. The series focuses on integrated solutions for small DC motors, specifically targeting fan applications where size and noise reduction are critical design constraints.

Replacement Considerations

Consult official substitution lists for equivalent three-phase sensorless drivers. Verify pin compatibility and electrical specifications before replacing with cross-reference models.
