LS24062RQ23

Overview

The Littelfuse LS24062RQ23 is a dual-channel bidirectional load switch IC designed for power distribution applications. It features two independent outputs with a maximum continuous current of 6 A per channel and a current limit of 3.5 A. The device operates within a supply voltage range of 3 V to 24 V, supporting a maximum system voltage of 28 V. It integrates comprehensive protection mechanisms including overvoltage, overcurrent, and thermal shutdown. The component is housed in a compact 16-pin QFN package measuring 2.5 mm by 3.2 mm, suitable for surface mount installation across an operating temperature range of -40 °C to +150 °C.

Feature Summary

• Bidirectional MOSFET control allows flexible power flow direction for each independent channel
• Integrated protection against overvoltage, overcurrent, and overheating conditions
• External pins enable customizable current limiting and discharge control settings

Applications

• Power distribution networks in automotive electronic systems
• Overload and short circuit protection for peripheral circuits
• Input voltage surge suppression in industrial equipment

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and tape/reel configuration match your assembly requirements. Confirm that the selected variant aligns with your manufacturing process specifications. Cross-reference the manufacturer's latest documentation to validate compliance with current environmental standards and RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring independent control of multiple power rails with bidirectional capability. Ensure the external current limit setting does not exceed the 3.5 A threshold to maintain device integrity. Verify that the thermal management design accommodates the specified junction temperature limits under maximum load conditions to prevent premature activation of thermal protection.

Part Context

This part belongs to the LS2406 series of power switch ICs from Littelfuse. The series focuses on reducing power loss during normal operation through low on-resistance switches. These devices are engineered to provide robust circuit protection while maintaining a small footprint, making them suitable for space-constrained designs in modern electronics.

Replacement Considerations

Consult official Littelfuse documentation for verified substitute part numbers. Do not assume functional equivalence between different series or manufacturers without validating pin compatibility and electrical parameters.
