A6A259KLBTR

Overview

The A6A259KLBTR is a latch driver manufactured by Allegro MicroSystems, designed for power distribution and load driving applications. It features an N-channel output configuration with eight outputs and a 3:8 input-to-output ratio. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum load voltage of 50V. It provides a typical output current of 350mA with a typical on-resistance of 1 ohm. The component is housed in a 24-SOIC package and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Supports addressable latch mode for flexible control logic
• Integrates fixed current limit protection for circuit safety
• Accepts both inverted and non-inverted input signals

Applications

• Automotive lighting systems requiring high-side or low-side switching
• Industrial load drivers needing isolated control interfaces
• Consumer electronics utilizing latch-based power distribution networks

Procurement Notes

Verify the specific suffix 'KLBTR' against official datasheets to confirm the 24-SOIC surface-mount package and tape-and-reel quantity. Ensure compatibility with 4.5V to 5.5V logic levels. Confirm humidity sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when an addressable latch interface is required for driving multiple loads from fewer control lines. The 350mA output capability suits moderate current applications. Verify that the 1-ohm on-resistance meets thermal dissipation constraints for the intended PCB layout and ambient operating conditions.

Part Context

This part belongs to the broader category of power management ICs and motor controllers offered by Allegro MicroSystems. It serves as a specialized interface solution bridging digital control logic with higher voltage power stages, distinct from standard MOSFET drivers or linear regulators.
