AP22653QW6-7

The automotive-compliant AP22653Q is a single-channel, precision-adjustable, current-limited switch optimized for applications that require accurate current limiting, or to provide up to 1.5A of continuous load current during heavy loads/short circuits. This device offers an adjustable current-limit threshold between 125mA and 1735mA (typ) via an external resistor. Current limit accuracy of ±7% can be achieved at high current-limit settings. The rise and fall times are controlled to minimize current surges during turn on/off. The device has fast short-circuit response time for improved overall system robustness. The device provides 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 protection; and controlled rise-time and undervoltage lockout functionality. A 6ms deglitch capability on the open-drain flag output prevents false overcurrent reporting and does not require any external components. The AP22653Q limits the output current to a safe level when the output current exceeds current-limit threshold and folds back the output current when subjected to short-circuit conditions. The device is available in the SOT26 (Type A1) package.
