Description
The AP2552A is a single channel precision adjustable current-limited switches optimized for applications that require up to 2.1A of continuous load current during heavy loads/short circuits. It offers a programmable current-limit threshold between 75mA and 2.35A via an external resistor. Current limit accuracy ±6% can be achieved at high current-limit settings.
It has a fast short-circuit response time for improved overall system robustness. It provides reverse current blocking and limiting, over-current, over-temperature and short-circuit protection, as well as control°C rise time and under-voltage lockout functionality.
A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components.
The AP2552A latches the output off when the output current exceeds current-limit threshold or the output voltage rises above the input voltage creating a reverse current to flow.
It is available in U-DFN2020-6 and SOT26 packages with green mold compounds.
Other members of this family include:
AP2553A has opposite polarity enable to AP2552A and has same function as AP2552A
AP2552/53 provide current limit function during over-current or reverse-voltage conditions
