A6810EA-T

Overview

The A6810EA-T is a bipolar latch driver manufactured by Allegro MicroSystems, designed for power switching applications. It features a 1:10 input-to-output ratio with ten high-side outputs. The device operates on a supply voltage between 3V and 5.5V and supports load voltages up to 60V. Each output provides a maximum current of 40mA. It utilizes non-inverting parallel or serial interfaces and is housed in a 20-SOIC package.

Feature Summary

• Provides ten independent high-side bipolar outputs for driving loads
• Features a 1:10 input-to-output ratio for efficient control
• Supports both parallel and serial interface configurations
• Includes internal protection mechanisms against short circuits

Applications

• Automotive lighting systems
• Solenoid valve control
• Relay driver circuits
• General industrial load switching

Procurement Notes

Verify the specific suffix EA-T against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices from Allegro MicroSystems before finalizing procurement plans.

Selection Notes

Select this component when a high number of isolated high-side outputs are required within a single package. Ensure the system logic levels match the 3V to 5.5V supply range. Verify that the 40mA per channel current rating meets the load requirements without external heat sinking.

Part Context

This part belongs to the A68xx series of latch drivers from Allegro MicroSystems. These devices are engineered for automotive environments, offering robust performance under varying temperature conditions. The series typically integrates protection features suitable for inductive loads found in vehicle electronics.

Replacement Considerations

Check for direct replacements within the A68xx family. Verify pin compatibility and electrical specifications before substituting with other Allegro drivers.
