Overview
The MIC502BM-TR is a bipolar motor driver manufactured by Microchip Technology, designed for brushless DC (BLDC) fan controller applications. It operates within a supply voltage range of 4V to 13.2V and features a parallel interface with low-side pre-driver output configuration. The component is housed in an 8-SOIC package (0.154"/3.90mm wide) and supports surface mount installation. It functions as a speed controller and is rated for an operating temperature range of -40°C to 85°C (TA).
Feature Summary
- Bipolar technology optimized for brushless DC motor control.
- Integrated low-side pre-driver for direct motor phase driving.
- Parallel interface simplifies digital control logic integration.
Applications
- Fan controller systems
- Brushless DC (BLDC) motor speed regulation
Procurement Notes
Verify component authenticity through authorized Microchip channels or certified distributors. Confirm the specific suffix matches the required tape-and-reel packaging format. Check current availability status as this part may be discontinued or subject to obsolescence notices. Ensure design-in compliance with RoHS and REACH regulations relevant to your region.
Selection Notes
Select this component when a dedicated bipolar driver for BLDC fans is required within the 4V-13.2V range. Consider the 8-SOIC footprint for PCB layout constraints. Evaluate thermal performance at the upper end of the specified operating temperature range. Verify that the parallel interface aligns with the host microcontroller's I/O capabilities.
Part Context
This part belongs to the MIC502 family of motor drivers from Microchip Technology. It is specifically engineered for low-voltage, low-power fan applications requiring precise speed control. The device integrates necessary drive circuitry into a compact surface-mount package, reducing external component count compared to discrete solutions.
Replacement Considerations
DigiKey lists this product as discontinued. No official substitute part numbers are documented in the provided source material. Designers should consult Microchip directly for potential pin-compatible alternatives or updated product recommendations.
