AP22652W6-7

The AP22652W6-7 from Diodes Incorporated is a single-channel, precision-adjustable, current-limited power switch designed for applications requiring precise current limiting or up to 2.1A of continuous load current during heavy loads or short circuits.

This device features a programmable current-limit threshold between 125mA and 2665mA via an external resistor, with current-limit accuracy of ±10% achievable at high settings. It provides a complete protection solution including reverse-current blocking and limiting, overcurrent, overtemperature, and short-circuit protection, along with controlled rise time and undervoltage lockout. The AP22652 and AP22653 variants limit output current during overcurrent conditions, while the AP22652A and AP22653A offer latch-off functionality.

The AP22652W6-7 operates within a voltage range of 3.0V to 5.5V and has a typical rise time of 0.5ms. It includes a 6ms deglitch capability on the open-drain flag output to prevent false overcurrent reporting. The device is available in a SOT-26 package, suitable for surface mount applications.

Key features include accurate adjustable current limit, fast short-circuit response time, reverse current blocking during shutdown, and ESD protection. It is suitable for applications such as set-top boxes, LCD TVs & monitors, residential gateways, and laptops.
