Disadvantages: - Limited maximum continuous current of 1.7A

Working Principles

The FPF1017 acts as a power switch by controlling the flow of current between the input voltage (VBAT) and the output (SW). When the EN pin is high, the MOSFET conducts, allowing current to flow from VBAT to SW. In case of overcurrent or excessive temperature, the protection features activate, interrupting the current flow to prevent damage.

Detailed Application Field Plans

The FPF1017 is suitable for various applications, including but not limited to: - Portable electronic devices - Battery-powered systems - Power management modules - IoT devices - Consumer electronics
