Automotive-Grade Ideal Diode Controller with Reverse Polarity Protection: MPQ5850
Smart Ideal Diode Controller Offers Robust Protection for Automotive Electronics
The MPQ5850-AEC1 is a 42V off-battery, smart ideal diode controller that can drive an external N-channel MOSFET to replace a Schottky diode for -36V reverse polarity protection. It minimizes power loss and enables a low minimum input voltage, making it ideal for applications such as digital clusters, infotainment, and ADAS. Compared to traditional solutions, the MPQ5850 features a compact solution and a much lower voltage drop, which delivers cooler thermals and more voltage overhead during cold and warm crank conditions.
Features:
- 20mV ultra-low dropout
- Reverse voltage blocking down to -36V
- Ability to operate under cold-crank conditions down to 0V
- Ultra-low 4µA quiescent current consumption in standby mode
- AC frequency rectification up to 100kHz
- Extremely fast response
- Strong gate drive capabilities
- Available in a tiny 8-pin TSOT23 (2mmx3mm) package
