A6B595KLW-T

Overview

The A6B595KLW-T is a discontinued power driver IC from Allegro MicroSystems, designed for medium-current or high-voltage peripheral loads. It integrates an 8-bit CMOS shift register with data latches and control circuitry. The device features DMOS open-drain outputs capable of sinking up to 150 mA continuously across all channels at ambient temperatures exceeding 85°C. It operates within a supply voltage range of 4.5V to 5.5V and supports serial input rates over 5 MHz. The component utilizes a 20-SOIC package.

Feature Summary

• Integrates an 8-bit CMOS shift register with data latches and control circuitry for direct microprocessor interfacing.
• Features DMOS open-drain outputs that allow cascade connections via a serial-data output pin.
• Utilizes copper lead frames and low on-state resistance to support continuous current sinking capabilities.

Applications

• Relay driving
• Solenoid control
• High-voltage peripheral power load management

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm availability of replacement parts such as the TPIC6B595DWR if production continuity is required. Ensure compliance with RoHS non-compliance requirements for existing inventory usage.

Selection Notes

Select this part only for legacy system maintenance where specific Allegro MicroSystems interface characteristics are mandatory. Evaluate thermal performance constraints regarding the 85°C ambient temperature limit for continuous operation. Consider the 20-SOIC footprint compatibility during PCB layout verification.

Part Context

This component belongs to the A6B595 series, which combines digital logic functions with power switching capabilities. It serves as a replacement for older models like the TPIC6B595N and TPIC6B595DW. The KLW suffix denotes the wide-body small-outline plastic package variant with gull-wing leads.

Replacement Considerations

The TPIC6B595DWR from Texas Instruments is listed as an upgrade replacement option.
