TPS259824ONRGER

Current Regulation/Management Overview

The TPS259824ONRGER is a single-channel hot-swap controller and electronic fuse manufactured by Texas Instruments. It operates within an input voltage range of 2.7V to 24V and supports a maximum output current of 15A. The device features a typical on-resistance (RON) of 2.7mΩ, ensuring low conduction losses. It provides precise current monitoring with ±1.5% accuracy at room temperature for output currents above 3A. The component is housed in a 24-VFQFN package measuring 4mm x 4mm with an exposed pad, designed for surface-mount installation.

Current Regulation/Management Feature Summary

• Integrates intelligent load current monitoring with high precision for accurate system feedback.
• Provides configurable fault response options including latch-off or auto-retry modes to manage transient events.
• Features fast short-circuit protection with rapid trip response times to safeguard downstream components.

Current Regulation/Management Applications

• Server standby power rail protection
• PCIe riser card and add-in card protection
• Fan module power management
• Router and switch optical module protection

Current Regulation/Management Procurement Notes

Verify the specific suffix 'ONRGER' against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics. Ensure that the ordering configuration matches the required overvoltage lockout threshold and retry settings. Cross-reference the package marking code to distinguish between genuine units and potential counterfeits during receipt inspection.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated eFuse capabilities is required for 24V systems. Consider the ±1.5% current monitor accuracy if precise load sensing is necessary. Evaluate the 2.7mΩ on-resistance against thermal dissipation requirements in the target application environment.

Current Regulation/Management Part Context

This part belongs to the TPS25982 family of smart electronic fuses from Texas Instruments. The family offers various configurations for overvoltage lockout thresholds and fault response behaviors. The TPS259824 variant specifically integrates fixed internal thresholds for certain protection parameters while maintaining adjustable current limiting via external resistors.
