A6A595KLB

Overview

The A6A595KLB is a power switch driver manufactured by Allegro MicroSystems, designed for low-side switching applications. It features an N-channel output configuration with a maximum continuous output current of 350mA per channel. The device supports a load voltage up to 50V and operates within a supply voltage range of 4.5V to 5.5V. It utilizes a 1:8 input-to-output ratio, allowing control of eight independent outputs through serial or parallel interfaces. 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 low-side N-channel drivers with fixed current limit protection
• Supports both serial and parallel interface modes for flexible system integration
• Includes thermal shutdown and over-current protection mechanisms

Applications

• Automotive lighting systems requiring multiple low-side switches
• Industrial load control circuits
• General-purpose power distribution management

Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm availability of qualified replacement components such as the TPIC6A595DW or TPIC6A595DWR from Texas Instruments. Ensure that any substitute device meets the required 50V load voltage rating and 350mA output current specifications. Validate pin compatibility and interface logic levels to prevent circuit redesign during transition.

Selection Notes

Select this component for designs requiring multiple low-side switches controlled via serial or parallel data lines. The 24-SOIC package suits surface-mount assembly processes. Verify that the system supply voltage remains within the 4.5V to 5.5V range. Consider the fixed current limit feature for protecting connected loads without external sensing resistors. Evaluate thermal performance given the high-temperature rating up to 125°C.

Part Context

This device belongs to the A6A595 family of power switch drivers from Allegro MicroSystems. The family provides integrated solutions for controlling multiple loads with minimal external components. The A6A595KLB specifically offers the SOIC package variant, distinguishing it from DIP versions like the A6A595KA. These drivers are engineered for reliability in automotive and industrial environments.

Replacement Considerations

The A6A595KLB is obsolete. Publicly confirmed substitutes include the TPIC6A595DW and TPIC6A595DWR from Texas Instruments. Verify electrical parameters and package dimensions match your design requirements before substitution.
