AP22655中文资料Precision Adjustable Current-Limited Power Switches数据手册Diodes规格书

描述 Description

The DIODES AP22654 and DIODES AP22655 are single channel precision adjustable current-limit switches optimized for applications that require precision current limiting, or to provide up to 3.1A of continuous load current during heavy loads/short circuits. These devices offer a pin-strapped current-limit threshold between 400mA and 3500mA (typ) via an external resistor. Current limit accuracy ±12% can be achieved at high current-limit settings. The rise and fall times are controlled to minimize current surges during turn on/off.

The devices have fast short-circuit response time for improved overall system robustness. They provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of short circuit, offering reverse current blocking and limiting, overcurrent, overtemperature and short-circuit protections, as well as controlled rise time and undervoltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false overcurrent reporting and does not require any external components.

AP22654 and AP22655 limit the output current to a safe level when the output current exceeds current-limit threshold.

Both devices are available in TSOT26 (Type A1) package.
