AP22653Q PRECISON-ADJUSTABLE CURRENT-LIMITED AUTOMOTIVE-COMPLIANT POWER SWITCH The automotive-compliant AP22653Q is a , single-channel, precisionadjustable, 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. Applications Automotive ECU Supply Rail Power Distribution and Switching Automotive ECU Supply Rail Precision Current Limiting The device is available in the SOT26 (Type A1) package. 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.
