The MPQ5817-AEC1 is an integrated smart diode designed to provide a compact solution for 200W electronic control unit (ECU) systems with the most simplified external circuity.

The device’s 2µA standby current makes it ideal for battery-powered applications. It integrates an N-MOSFET and an internal charge pump, which supports nominal loads up to 15A of continuous current and minimizes power loss between the input and output. Ultra-fast transient response ensures that the MPQ5817-AEC1 can rectify the AC frequency up to 100kHz.

In addition to reverse-polarity protection and reverse-pulse protection, the MPQ5817-AEC1 also provides multiple diagnostics during fault conditions, such as under-voltage (UV), over-voltage (OV), over-current (OC), and over-temperature (OT) conditions.

With an extremely low under-voltage lockout (UVLO) threshold, the MPQ5817-AEC1 provides a wide operating range to meet the harsh start-up conditions defined in ISO 16750 standards. The device also supports cold-crank voltages down to 0V.

The MPQ5817-AEC1 is available in a QFN-21 (4mmx5mm) package, and is AEC-Q100 qualified.
