A6B595KLWTR-T

Overview

The A6B595KLWTR-T is an 8-bit serial-input DMOS power driver integrating a CMOS shift register, data latches, and control circuitry. It features eight open-drain outputs capable of sinking up to 150 mA continuously with a typical on-state resistance of 5 ohms. The device supports a minimum output clamp voltage of 50 V and operates within a temperature range of -40°C to +85°C. Packaged in a 20-SOIC wide-body format, it allows direct interfacing with microprocessor systems via serial data inputs exceeding 5 MHz.

Feature Summary

• Integrates an 8-bit CMOS shift register and data latches for direct microprocessor interfacing
• Features eight DMOS open-drain outputs designed for medium-current peripheral loads
• Supports cascade connections through a dedicated CMOS serial-data output pin

Applications

• Relay driving circuits
• Solenoid actuation systems
• High-voltage peripheral power load control

Procurement Notes

Verify the specific suffix KLWTR-T against official Allegro MicroSystems documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 20-SOIC wide-body package. Confirm that the 150 mA continuous sink current per output meets system requirements without additional thermal management solutions.

Selection Notes

Select this component when an 8-channel low-side switch with integrated serial shifting logic is required. It serves as a functional replacement for legacy TPIC6B595N and TPIC6B595DW devices. Consider the 5-ohm typical on-resistance and 50 V clamp voltage when designing for high-efficiency power delivery to inductive or resistive loads.

Part Context

This part belongs to the 6B595 family of DMOS power drivers manufactured by Allegro MicroSystems. The series combines digital logic functions with power switching capabilities in a single IC. The KLW variant specifically denotes the wide-body small-outline plastic package with gull-wing leads, distinguishing it from dual-in-line package options within the same functional family.

Replacement Considerations

Officially documented replacements include the TPIC6B595N and TPIN6B595DW. Verify pinout compatibility and thermal performance characteristics before substituting these legacy parts in existing designs.
