A6810ELW

Overview

The A6810ELW is a bipolar latched driver IC manufactured by Allegro MicroSystems. It features a 1:10 input-to-output ratio with ten high-side outputs. The device operates on a supply voltage of 3V to 5.5V and supports a maximum load voltage of 60V. Each output provides a peak current of 40mA. It utilizes non-inverting inputs and supports both parallel and serial interfaces. The component is housed in a 20-SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

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

Applications

• Bipolar stepper motor control systems
• High-side switching applications requiring multiple channels
• Industrial automation equipment drivers
• Automotive electronic control modules

Procurement Notes

Verify the specific suffix ELW to confirm the 20-SOIC package and commercial grade temperature rating. Confirm RoHS compliance status as documentation indicates potential non-compliance. Check current product lifecycle status, as this part may be discontinued or subject to last-time buy restrictions. Ensure the selected variant matches the required interface type for your system design.

Selection Notes

Select this component when a high number of high-side outputs are required from a single controller. The 1:10 ratio reduces pin count compared to individual drivers. Verify that the 40mA output current meets the load requirements. Consider the 60V load voltage limit for compatibility with the target power supply. Evaluate the need for serial versus parallel interfacing based on available microcontroller resources.

Part Context

This device belongs to the A68xx series of bipolar latched drivers designed for controlling stepper motors and other inductive loads. These components integrate multiple driver channels into a single package to simplify PCB layout. The series is characterized by its ability to handle bipolar currents and provide robust protection features suitable for demanding industrial and automotive environments.

Replacement Considerations

Check for direct substitutes within the A68xx family that offer similar channel counts and voltage ratings. Verify pinout compatibility if replacing with variants having different package options. Ensure any alternative maintains the 1:10 ratio and high-side output configuration.
