The EVQ5850-J-00A is an evaluation board designed to demonstrate the capabilities of the MPQ5850, a 36V, smart diode controller with reverse protection.

The MPQ5850 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), which makes the MPQ5850 well-suited for cold-crank conditions in automotive applications. The 4μA shutdown current (I_SHDN) also makes the device ideal for battery-powered applications. The ultra-fast transient response meets stringent ISO16750 requirements.

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

The EVQ5850-J-00A is fully assembled and tested. The MPQ5850 is available in a TSOT23-8 (2mmx3mm) package.
