Overview
The A6595KLW is an obsolete 8-bit serial-input DMOS power driver manufactured by Allegro MicroSystems. It integrates a CMOS shift register, data latches, control circuitry, and eight N-channel low-side power outputs in a 20-SOIC package. The device supports a supply voltage range of 4.5V to 5.5V and handles load voltages up to 50V maximum. Each output provides a typical on-resistance of 1.3 ohms and can deliver a maximum current of 250mA simultaneously across all channels. Operating temperatures span from -40°C to 125°C.
Feature Summary
- Integrates an 8-bit serial input shift register with accompanying data latches for simplified interface control
- Features eight N-channel DMOS power outputs configured as low-side drivers for medium-current loads
- Includes internal control circuitry designed for driving relays, solenoids, and high-voltage peripheral power loads
Applications
- Relay driving circuits
- Solenoid actuation systems
- Medium-current peripheral power load management
Procurement Notes
Verify component obsolescence status before design finalization. Confirm RoHS compliance requirements against the non-compliant specification. Validate pinout compatibility with replacement devices such as TPIC6595DWR. Ensure thermal management aligns with the specified operating temperature range. Review datasheet revisions for any packaging or electrical parameter changes.
Selection Notes
Select this component only if legacy compatibility with the 6595 series is required. Evaluate the 1.3 ohm on-resistance for appropriate heat dissipation at full load. Consider the 250mA simultaneous output capability for total system current budgeting. Assess the 20-SOIC package constraints for PCB layout. Compare performance metrics against active replacements like the TPIC6595DWR.
Part Context
This part belongs to the A6595 family of 8-bit serial-input DMOS power drivers. It serves as a direct functional replacement for older parts like the TPIC6595N and TPIC6595DW. The device is designed for applications requiring multiple low-side switches controlled via a simple serial interface. It consolidates logic and power stages into a single integrated circuit.
Replacement Considerations
TPIC6595DWR and TPIC6595DWRG4 are confirmed direct replacements. L6225D is listed as a similar alternative. Verify pin-to-pin compatibility and electrical specifications when substituting.
