A6810SA-T

Overview

The A6810SA-T is a bipolar latch driver manufactured by Allegro Microsystems, designed for driving external power switches in motor control applications. It features a 1:10 input-to-output ratio and provides ten high-side outputs. The device operates with a supply voltage range of 3V to 5.5V and supports load voltages up to 60V. It utilizes non-inverting parallel or serial interfaces and delivers a maximum output current of 40mA per channel. The component is housed in a 20-SOIC package and functions within an operating temperature range of -20°C to +85°C.

Feature Summary

• Integrates a 1:10 gain stage to amplify low-current logic signals for driving multiple external power devices
• Provides ten independent high-side output channels configured as a latch driver
• Supports flexible system integration through selectable parallel or serial interface modes

Applications

• Brushed DC motor drive systems requiring multi-phase commutation
• Solenoid valve arrays controlled by low-power microcontrollers
• Industrial automation equipment utilizing external switching topologies

Procurement Notes

Verify the specific suffix 'SA' against the manufacturer's official documentation to confirm pinout compatibility and package dimensions. Confirm that the 20-SOIC footprint matches the target PCB layout. Ensure the design accounts for the 40mA output current capability when selecting external MOSFETs. Check for any recent product change notices regarding the SOIC tape and reel specifications.

Selection Notes

Select this component when a single logic input must control ten separate high-side loads efficiently. The internal 1:10 amplification reduces the burden on the upstream controller compared to direct drive solutions. Consider the 60V load voltage rating to ensure adequate headroom for the application's supply rails. Evaluate the thermal performance requirements associated with the 20-SOIC package for the intended ambient conditions.
