MPQ5850 Datasheet 36v Smart Diode Controller

Manufacturer: Monolithic Power Systems

Overview: 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.

General 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 20mV 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.

Key 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 100kHz o Strong Gate Drive Ability: 170mA PullUp and 430mA 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.
