A6A595KLBTR

Overview

The A6A595KLBTR is a discontinued power switch and driver integrated circuit manufactured by Allegro Microsystems. It features an N-channel output configuration with a 1:8 input-to-output ratio, designed for low-side switching applications. The device supports parallel and serial interfaces and operates within a supply voltage range of 4.5V to 5.5V. It provides a maximum output current of 350mA per channel and includes fixed current limit fault protection. The component is housed in a 24-SOIC surface-mount package and is rated for an operating temperature range from -40°C to 125°C.

Feature Summary

• Integrates eight independent N-channel low-side drivers with a single-input latch architecture
• Supports both parallel and serial interface control modes for flexible system integration
• Includes built-in fixed current limit protection to safeguard against load faults

Applications

• Low-side switching for automotive lighting systems
• Control of solenoids and relays in industrial machinery
• Power distribution management in consumer electronics

Procurement Notes

This specific part number is officially discontinued and no longer in production. Verification of availability should focus on surplus distributors or secondary market sources rather than standard retail channels. Buyers must confirm the authenticity and storage history of existing stock due to the component's end-of-life status. Cross-referencing with equivalent active components is recommended for new designs.

Selection Notes

Designers requiring this functionality should consider alternative active components that offer similar 1:8 latch driver capabilities. Key selection criteria include verifying compatibility with the required 4.5V to 5.5V supply voltage and ensuring the target application can accommodate the 350mA output current limit. Package footprint compatibility with the 24-SOIC form factor should be assessed when evaluating replacement options.

Part Context

The A6A595KLBTR belongs to the A6A595 family of power switches, which are engineered for high-density switching applications. This series utilizes N-channel technology to provide efficient low-side control. The component represents a legacy solution within Allegro's portfolio, previously utilized in applications requiring multiple synchronized outputs controlled via simple serial or parallel logic signals.

Replacement Considerations

Texas Instruments TPIC6A595DW and TPIC6A595DWR are documented as similar replacement alternatives for this discontinued component.
