FPF2116

FPF2116 Description

The FPF2116 from onsemi is a high-side P-channel power distribution switch designed for general-purpose load switching applications. Part of the IntelliMAX™ series, this 1:1 ratio switch operates within a 1.8V to 5.5V load voltage range, delivering up to 200mA of continuous output current with a low 125mOhm (typical) Rds(on) for minimal power loss. The device integrates advanced protection features, including fixed current limiting, over-temperature shutdown, reverse-current blocking, and undervoltage lockout (UVLO), ensuring robust system reliability.

FPF2116 Features

• High-Side Configuration: Simplifies circuit design by eliminating the need for an external supply (Vcc/Vdd).
• Auto-Restart & Status Flag: Automatically recovers from faults and provides diagnostic feedback via a flag output.
• Compact & Reliable: Offered in a SOT23-5 package with MSL 1 (Unlimited) moisture sensitivity, suitable for automated assembly.
• Compliance: ROHS3 and REACH compliant, meeting global environmental standards.
• Low Power Dissipation: Optimized Rds(on) reduces heat generation in space-constrained designs.

FPF2116 Applications

• Portable Electronics: Ideal for smartphones, tablets, and wearables due to its low-voltage operation and minimal footprint.
• USB Power Management: Protects USB peripherals from overcurrent and reverse-polarity events.
• Battery-Powered Systems: Enhances safety in IoT devices and wireless sensors with its auto-restart capability.
• Industrial Controls: Suitable for PLC modules and low-power actuators requiring fault-tolerant switching.

Conclusion of FPF2116

The FPF2116 stands out for its integration of protection features, low on-resistance, and compact form factor, making it a versatile solution for modern power management challenges. While marked obsolete, its design advantages remain relevant for legacy systems or applications prioritizing reliability. Engineers should evaluate alternative IntelliMAX™ devices for new designs while leveraging the FPF2116’s proven performance in existing implementations.
