Overview
The TB6631FNG,EL is a Bi-CMOS parallel motor driver IC designed for Brushless DC (BLDC) motor control. It operates within a supply voltage range of 7V to 16.5V and utilizes a 30-pin SSOP package. The device implements 3-phase full-wave sine-wave PWM control with an internal triangular-wave generator operating at a carrier frequency of fosc/252 Hz. It features lead angle control adjustable from 0° to 58° in 32 steps. The component includes under-voltage lockout (UVLO) protection and supports low current operation.
Feature Summary
- Implements 3-phase full-wave sine-wave PWM control for smooth BLDC motor operation
- Integrates an internal triangular-wave generator for carrier frequency generation
- Provides programmable lead angle control with 32 discrete adjustment steps
- Includes under-voltage lockout protection for system reliability
Applications
- Brushless DC motor control systems
- Sine-wave PWM driven BLDC applications
- Devices requiring integrated lead angle adjustment
Procurement Notes
Verify the specific ordering suffix EL against the manufacturer's official documentation to confirm packaging and compliance details. Ensure the input voltage requirements align with the 7V to 16.5V operational range specified for this component. Confirm the 30-pin SSOP package type matches the target PCB design constraints before procurement.
Selection Notes
Select this component for applications requiring integrated sine-wave PWM control without external waveform generation circuitry. The built-in lead angle control simplifies tuning for optimal motor performance. Verify that the required supply voltage falls within the specified 7V to 16.5V range and that the thermal characteristics of the SSOP-30 package are suitable for the intended power dissipation levels.
