TBD62003APG

Overview

The TBD62003APG is a low-side gate driver featuring a seven-channel DMOS transistor array. It operates with an inverting configuration and supports a maximum load voltage of 50V. The device delivers a continuous output current of 500mA per channel. It functions within a supply voltage range of 2.5V to 25V and withstands operating temperatures from -40°C to +85°C. Key timing parameters include a maximum turn-on delay of 0.4µs and a maximum turn-off delay of 0.8µs. Power dissipation is rated at 1.47W, and it utilizes a DIP-16 through-hole package.

Feature Summary

• Integrates seven independent low-side DMOS output channels for driving multiple loads simultaneously.
• Includes built-in clamp diodes on each output terminal to protect against voltage spikes from inductive loads.
• Features an inverting logic interface that simplifies control signal connection to standard digital outputs.
• Provides robust thermal performance with specified power dissipation capabilities for sustained operation.

Applications

• Driving stepper motors and solenoids in industrial automation systems
• Controlling relay banks in home appliance control boards
• Actuating valves and pumps in fluid management equipment

Procurement Notes

Verify the specific suffix designation to confirm the package type, as the TBD62003 series includes surface-mount variants like AFWG and AFNG alongside this through-hole DIP version. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement specifications. Ensure the ordering quantity aligns with the factory tube packaging format associated with this specific part number.

Selection Notes

Select this component when a high-current low-side switching solution with integrated flyback protection is required. The inverting input logic must be compatible with the system's microcontroller or logic level. Consider the DIP-16 footprint constraints during PCB layout. This part is suitable for applications requiring moderate current handling without the need for external heat sinking under typical duty cycles.
