MPQ5850-AEC1

36V, Smart Diode Controller with Reverse Protection, AEC-Q100 Qualified

Description

The MPQ5850-AEC1 is a smart diode controller that can drive an external N-channel MOSFET to replace a Schottky diode for reverse input protection. The device’s 20mV ultra-low dropout minimizes power loss and enables a low minimum input voltage (V_IN). This makes the MPQ5850-AEC1 well-suited for automotive cold-crank conditions.

The shutdown current (4μA) also makes the device ideal for battery-powered applications. The ultra-fast transient response meets stringent ISO16750 requirements.

The MPQ5850-AEC1 integrates an internal boost converter to provide a boost voltage that turns on the external N-channel MOSFET, even at a low V_IN. An open-drain, power good (PG) signal indicates whether the external N-channel MOSFET is on fully.

The MPQ5850-AEC1 is available in a TSOT23-8 (2mmx3mm) package.
