Description

The AP2337 is single channel current-limited integrated highside power switches 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 heavy capacitive loads and the prospect of short circuit. It offers reverse current blocking, over-current, over-temperature and short-circuit protection, as well as control°C rise time and under-voltage lockout functionality. The device is available in SOT23 package.
