A6841SLW-T

Overview

The A6841SLW-T is a bipolar latch driver manufactured by Allegro MicroSystems, designed for power switching applications. It features an 8-channel output configuration with a 1:8 input-to-output ratio. The device operates within a supply voltage range of 3V to 5.5V and supports load voltages up to 50V maximum. It provides a maximum output current of 600mA per channel. The component utilizes parallel and strobe pulse interfaces for control. It is housed in a 24-SOIC surface-mount package with a width of 7.50mm. The operational temperature range extends from -20°C to +85°C.

Feature Summary

• Supports bipolar latch driving capabilities for precise control of external loads
• Features an 8-channel output architecture driven by a single input signal
• Integrates low-side output configuration for efficient power management
• Utilizes parallel and strobe pulse interface protocols for data transmission

Applications

• Bipolar stepper motor drive systems
• High-density LED matrix lighting arrays
• Industrial solenoid valve control circuits
• Relay bank switching mechanisms

Procurement Notes

Verify the specific suffix 'SLW' against the manufacturer's official datasheet to confirm the exact package dimensions and tape-and-reel specifications. Ensure that the 24-SOIC footprint matches your PCB layout requirements. Confirm that the operating temperature range of -20°C to +85°C meets your environmental constraints. Check for RoHS compliance status if required by your assembly standards.

Selection Notes

Select this component when a high-channel-count driver is needed for bipolar loads. The 600mA output capability suits moderate current applications without requiring external heat sinking in most cases. The 50V load rating allows compatibility with standard industrial voltage levels. Consider the 24-SOIC package size for space-constrained designs where through-hole options are not feasible.

Part Context

This part belongs to the A6841 series of power drivers from Allegro MicroSystems. The series is characterized by its ability to handle multiple channels efficiently. The SLW suffix specifically denotes the 24-SOIC surface-mount package variant. This family is commonly used in applications requiring reliable switching of inductive or resistive loads with minimal external components.

Replacement Considerations

Publicly confirmed substitute part numbers for the A6841SLW-T are not available in the provided documentation. Verify compatibility with alternative drivers based on pinout, voltage ratings, and current capacity before substitution.
