TB6549PG(O)

Overview

The TB6549PG(O) is a full-bridge driver IC for DC motors manufactured by Toshiba Semiconductor and Storage. It utilizes an LDMOS structure for output transistors to enable high-efficiency drive through low ON-resistance and PWM drive systems. The device supports four operational modes: clockwise, counter-clockwise, short brake, and stop, selected via IN1 and IN2 inputs. It operates within a power supply voltage range of 10V to 30V and features a 25-pin HZIP package.

Feature Summary

• Integrates LDMOS output transistors for high-efficiency motor driving
• Supports PWM drive system for precise control
• Offers four selectable operation modes including CW, CCW, short brake, and stop

Applications

• DC motor control in industrial automation equipment
• Motion control systems requiring bidirectional rotation
• Applications necessitating short brake functionality for rapid stopping

Procurement Notes

Verify the specific suffix (O) against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement channel provides authentic Toshiba Semiconductor and Storage products with valid traceability documentation. Cross-reference the 25-pin HZIP package dimensions with your PCB layout requirements before finalizing orders.

Selection Notes

Select this component when a robust full-bridge driver with integrated LDMOS technology is required for DC motors. It is suitable for applications needing simple interface control via two input pins for direction and braking. Consider the 30V maximum supply voltage and current capabilities relative to the motor load specifications to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the TB6549 series, which includes variants like TB6549FG and TB6549HQ. These are designed as full-bridge drivers for DC motors using Bi-CMOS or LDMOS processes. The series emphasizes efficiency and ease of use through direct PWM interface and multiple operational modes, catering to general-purpose motor control needs.

Replacement Considerations

Direct substitutes include TB6549FG and TB6549HQ from the same family. Verify package compatibility (HZIP vs. other formats) and electrical parameter alignment, particularly supply voltage ranges and output current ratings, before substitution.
