FPF2488UCX

Battery Management Overview

The FPF2488UCX is a dual-channel, low RDS(ON) load switch manufactured by Fairchild Semiconductor. It features an integrated current limit and thermal shutdown protection for robust system reliability. The device operates with a supply voltage range of 2.5V to 5.5V and supports input voltages up to 5.5V. Each channel provides independent control via enable pins, allowing precise power sequencing. The component utilizes a compact UCSP-6 package, optimizing board space while maintaining high efficiency in portable electronics and consumer applications requiring efficient power management.

Battery Management Feature Summary

• Dual-channel architecture with independent enable controls for flexible power distribution
• Integrated over-current protection and thermal shutdown mechanisms ensure safe operation under fault conditions
• Low on-resistance design minimizes power loss and heat generation during normal operation

Battery Management Applications

• Portable electronic devices requiring efficient power routing
• Consumer electronics with multiple voltage domains
• Peripheral power switching in mobile platforms

Battery Management Procurement Notes

Verify the specific suffix 'UCX' corresponds to the tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the manufacturer designation aligns with Fairchild Semiconductor or its successor entities to ensure authenticity. Cross-reference the date code and lot marking against authorized distributor records to prevent counterfeit components. Ensure storage conditions comply with moisture sensitivity level requirements prior to assembly.

Battery Management Selection Notes

Select this component when dual independent load switches are required within a single package footprint. Evaluate the maximum continuous current rating against the load requirements to ensure adequate headroom. Consider the operating voltage range compatibility with the system's main supply rail. Assess the need for integrated protection features to simplify bill of materials and reduce external component count.

Battery Management Part Context

This part belongs to the FPF24xx series of dual load switches designed for low-voltage applications. It complements single-channel variants by offering two isolated outputs in a minimal outline package. The series targets markets demanding high integration and space-constrained designs. Related parts may differ in current ratings, package types, or additional features like discharge resistors.

Battery Management Replacement Considerations

Direct substitutes must match the dual-channel configuration, UCSP-6 package, and electrical specifications. Verify pin-to-pin compatibility before substitution. Check if alternative manufacturers offer equivalent functionality with identical thermal and current limits. Ensure any replacement maintains the same enable logic and protection thresholds.
