AP2331 0.2A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH Description Pin Assignments The AP2331 is a single channel current-limited integrated high-side (Top View) power switcher optimized for hot-swap applications. The devices have fast short-circuit response time for improved overall system robustness and provide a complete protection solution for application subject to GND heavy capacitive loads and the prospect of short circuit. It offers reverse-current blocking, over-current, over-temperature and short- IN voltage circuit protection, as well as controlled rise time and under- lockout functionality. OUT The device is available in SOT23, SC59 and U-DFN2020-3 packages. SOT23 Features Input Voltage Range: 2.7V - 5.2V (Top View) Fast Short-Circuit Response Time 0.4A Accurate Current Limiting 250m On-Resistance GND Reverse-Current Blocking Built-In Soft-Start with 0.7ms Typical Turn-On Time IN Over-Current Protection Over-Voltage Protection OUT Short-Circuit and Thermal Protection ESD Protection: 3KV HBM, 300V MM SC59 Ambient Temperature Range: -40C to +85C Available in Green Molding Compound (No Br, Sb) Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) ( Top View ) IN Halogen and Antimony Free.
