A3908EEETR-T

Overview

The A3908EEETR-T is a brushed DC motor driver from Allegro MicroSystems, designed for low-voltage applications with an operating supply voltage range of 3V to 5.5V. It features a full-bridge output configuration capable of delivering up to 500mA of continuous output current. The device operates within a temperature range of -40°C to +85°C and utilizes a compact 8-DFN (2x2) surface-mount package. It integrates power MOSFET technology for efficient control.

Feature Summary

• Integrates full bridge driver with complete control and power stages
• Supports bidirectional operation for brushed DC motors
• Includes built-in overcurrent protection mechanisms

Applications

• Brushed DC motor control in consumer electronics
• Valve actuation systems
• Solenoid driving applications

Procurement Notes

Verify the specific suffix EEETR-T against the manufacturer datasheet to confirm packaging type and tape specifications. Ensure compatibility with the target PCB footprint for the 8-DFN package. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Selection Notes

Select this component for low-voltage brushed DC motor applications requiring integrated control and power stages. Consider the 500mA current limit and 3V-5.5V supply range when designing the power circuit. Evaluate thermal performance requirements given the small DFN package size for heat dissipation.

Part Context

This part belongs to the A3908 series of motor drivers from Allegro MicroSystems. It is specifically engineered as a copper wire version variant within the broader product line, focusing on cost-effective solutions for simple motor control tasks in portable and battery-powered devices.

Replacement Considerations

Check for direct pin-to-pin replacements within the same Allegro family that may offer updated packaging or slight parameter variations. Verify functional equivalence regarding voltage ranges and current capabilities before substituting.
