AP2553数据手册集成电路（IC）的配电开关负载驱动器规格书PDF

描述 Description

The AP2553 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 AP2553 limits the output current to a safe level when the output current exceeds current-limit threshold.
It is available in U-DFN2020-6 and SOT26 packages with green mold compounds.


Other members of this family include:
AP2552 has opposite polarity enable to AP2553 and limits the output current to a safe level when the output current exceeds current-limit threshold

AP2552A/53A provides latch-off function during over-current or reverse-voltage conditions
