A8585KLKTR-T

Overview

The A8585KLKTR-T is an automotive-grade synchronous buck regulator from Allegro MicroSystems, designed for low quiescent current applications. It operates within a wide input voltage range and provides a single adjustable output. The device is housed in a SOIC-10 package with an exposed pad for thermal management. It features integrated protection mechanisms including overcurrent, overtemperature, and undervoltage lockout. The component is moisture sensitive and supplied in a reel format.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Low quiescent current architecture for efficient standby operation
• Integrated synchronous rectification for improved efficiency
• Comprehensive protection against overcurrent and thermal overload

Applications

• Battery-powered automotive systems requiring low power consumption
• Infotainment and display backlight power regulation
• Sensor node power supply in connected vehicle architectures
• Always-on memory or control module backup power

Procurement Notes

Verify the specific suffix and tape-and-reel configuration against the manufacturer's latest datasheet before ordering. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure the SOIC-10 footprint matches the design board layout precisely. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component when automotive reliability and minimal static power draw are critical. The SOIC-10 package suits designs with moderate thermal dissipation needs. Compare input voltage ranges and output current capabilities against system demands. Consider the trade-off between external component count and efficiency requirements for the specific application environment.

Part Context

This part belongs to the A8585 series of low IQ buck regulators. It is distinct from higher current variants like the A8589 or legacy models such as the A8580. The series focuses on efficiency in low-power automotive contexts rather than high-power distribution.

FAQ

Is the A8585KLKTR-T suitable for high-current motor control applications?

No, it is designed for low quiescent current applications and typically supports lower output currents compared to high-power buck regulators.

What is the maximum operating temperature for this regulator?

The device is rated for an ambient operating temperature range extending up to 125°C, consistent with automotive grade specifications.
