A6841SLWTR-20-T

Overview

The A6841SLWTR-20-T is a medium-power serial-input latched sink driver integrated circuit manufactured by Allegro MicroSystems. It utilizes the DABiC-5 merged bipolar/CMOS/DMOS process to combine low-power CMOS logic inputs with bipolar output power drivers. This device features an 8-channel output configuration with a 1:8 input-to-output ratio, housed in a 20-SOIC package. It operates with a supply voltage range of 3V to 5.5V and supports a maximum load voltage of 50V. The component provides a maximum output current of 500mA per channel and functions as a low-side latch driver with non-inverting inputs.

Feature Summary

• Integrates low-power CMOS logic inputs with bipolar output power drivers for enhanced interface flexibility
• Features serial-input latched sink driver architecture for peripheral power control
• Utilizes DABiC-5 merged bipolar/CMOS/DMOS process technology

Applications

• Peripheral power driver applications
• Interface systems requiring flexibility beyond standard logic buffers
• Power driver arrays

Procurement Notes

Verify component status carefully as this specific part number is listed as obsolete or discontinued in major distributor databases. Confirm availability of alternative packages or updated series from Allegro MicroSystems if current stock is required for production. Ensure compatibility with existing 20-SOIC footprints when evaluating replacements.

Selection Notes

Select this component for designs requiring high-current bipolar outputs driven by low-power CMOS logic without external level shifting. The serial input capability reduces pin count compared to parallel interfaces. Consider the 500mA output capacity and 50V load voltage rating against specific load requirements. Verify thermal management needs for the 20-SOIC package under continuous operation conditions.

Part Context

The A6841 belongs to the A68xx family of medium-power serial-input latched sink drivers from Allegro MicroSystems. These devices are designed to bridge the gap between standard logic buffers and heavy-duty power driver arrays. The family leverages proprietary DABiC-5 technology to offer versatile solutions for driving various peripheral loads efficiently.
