TC78B015FTG,EL

Overview

The TC78B015FTG,EL is a three-phase brushless DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates power MOSFETs capable of delivering up to 3A output current with a maximum supply voltage of 25V. The device operates within a temperature range of -40°C to +105°C and utilizes a 36-WQFN package with an exposed pad for thermal management. Key electrical features include under-voltage lockout (UVLO), over-current detection (ISD), and thermal shutdown (TSD) protections.

Feature Summary

• Integrates high-side and low-side power MOSFETs for efficient three-phase BLDC motor control
• Includes built-in protection mechanisms such as under-voltage lockout, over-current detection, and thermal shutdown
• Supports PWM input signals for precise speed and direction management

Applications

• Three-phase brushless DC motor control in industrial automation equipment
• Fan and pump drivers in home appliances
• Precision motion control systems requiring integrated power stages

Procurement Notes

Verify the specific suffix EL against the manufacturer's latest datasheet to confirm packaging and tape specifications. Ensure the ordering part number matches the required quantity format, as distributors may list standard reel sizes. Cross-reference the RoHS status and moisture sensitivity level with current environmental compliance documents before finalizing procurement.

Selection Notes

Select this component when designing circuits for three-phase BLDC motors requiring integrated power switching without external gate drivers. Consider the 36-WQFN package size for space-constrained PCB layouts. Evaluate the 3A continuous current rating against peak load requirements and ensure adequate thermal dissipation via the exposed pad for operation at elevated ambient temperatures.

Part Context

This part belongs to the TC78B015 series of brushless motor control drivers from Toshiba. It is designed specifically for applications needing compact, high-efficiency motor control solutions. The series typically offers integrated protection features to enhance system reliability in consumer and industrial environments.

Replacement Considerations

Check Toshiba's official replacement guide for direct pin-compatible alternatives within the TC78B0xx series. Verify that any substitute maintains the same 3-phase architecture, voltage ratings, and package dimensions to ensure mechanical and electrical compatibility.
