MPQ5850 Datasheet | Monolithic Power Systems

DESCRIPTION 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 20m V ultra-low dropout minimizes power loss and enables a low minimum input voltage, which makes the MPQ5850 well-suited for cold-crank conditions in automotive applications. The 4μA shutdown current also makes the device ideal for batterypowered 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 a low input voltage (VIN). An open-drain, power good signal indicates when the external N-channel MOSFET is fully on. The MPQ5850 is available in a TSOT23-8 (2mmx3mm) package. 36V, Smart Diode Controller with Reverse Protection, AEC-Q100 Qualified FEATURES - Built to Handle Tough Automotive Transients: o -36V Blocking Voltage o Load Dump Up to 42V o Cold Crank Down to 0V o Rectifies AC Frequency Up to 100k Hz o Strong Gate Drive Ability: 170m A Pull Up and 430m A Pull-Down - Extended Vehicle Battery Life: o Low Quiescent Current in Standby Mode (4μA) o Low Quiescent Current in Steady State (30μA) - Reduced Board Size: o Available in a TSOT23-8 (2mmx3mm) Package - Additional Features : o 20m V Ultra-Low Dropout o Integrates a Boost Converter o Power Good (PG) Indication for RES Out of Regulation, Fast Pull-Up, and Part Disabling o Available in AEC-Q100 Grade 1 APPLICATIONS - Automotive System Protection - Automotive ADAS Systems (Cameras) - Automotive Infotainment Systems, Including Digital Clusters and Head Units - Battery-Powered Systems All MPS parts are lead-free, halogen-free, and adhere to the Ro HS directive.
