A6595KA

Overview

The A6595KA 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 DMOS outputs in a 20-DIP package. The device supports a supply voltage range of 4.5V to 5.5V and handles load voltages up to 50V. Each output provides a maximum current of 350mA with a typical on-resistance of 1 ohm. It operates within a temperature range of -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 designed for driving medium-current or high-voltage peripheral loads.
Includes fixed current limit fault protection to safeguard the device during overcurrent conditions.

Applications

Relay driver circuits
Solenoid actuation systems
High-voltage peripheral power load switching

Procurement Notes

Verify component obsolescence status before integration into new designs. Confirm that replacement components meet all electrical specifications, including voltage ratings and current capabilities. Ensure thermal management requirements are addressed due to the specified operating temperature range. Validate pin compatibility if substituting with alternative packages.

Selection Notes

Select this component only for legacy system maintenance or repair where original part matching is critical. Evaluate alternatives based on pinout compatibility and electrical parameter equivalence. Consider surface-mount options if board space constraints exist in updated designs. Review datasheet limitations regarding simultaneous output current sharing.

Part Context

This part belongs to the A6595 family of 8-bit serial-input DMOS power drivers. It serves as a direct replacement for older TPIC6595N devices. The family is characterized by low power consumption and robust output clamping capabilities. It is distinct from addressable variants like the A6A259 which utilize different control interfaces.
