About This Product

■Summary

The MPQ2022A-AEC1 is a dual-channel low-dropout (LDO) regulator with digital interface and memory. The device provides phantom power to low-noise amplifiers (LNAs) for active antennas in automotive systems and can operate from cold-crank (4.5V) to load-dump (40V) input voltage (VIN) conditions. The MPQ2022A-AEC1 provides up to 300mA per channel with excellent load and line regulation. The low quiescent current (quiescent current) of 35μA makes the device suitable for always-on power supplies. The MPQ2022A-AEC1's dual LDO outputs are configurable via the digital interface. The output voltage (VOUTx, where x=1 or 2) can be set between 1V and 13.6V. You can adapt various parameters by writing settings to the device. For bench evaluation, various settings can be easily configured through the digital interface instead of changing external components. Once optimally configured, settings can be permanently stored in memory. The MPQ2022A-AEC1 is available in a QFN-16 (4mm x 4mm) package with wettable flanks.

■Powerful digital functions

・No external resistor network for output voltage (VOUT) setting ・Dual configurable low dropout (LDO) regulators ・300mA continuous output current (IOUTx) per channel ・VOUTxx range from 1V to 13.6V ・Overheat protection ・Serial digital interface ・Analog-to-digital converter (ADC) for LDO output voltage and load current ・Multiple page memory

■Designed for automotive applications

AEC-Q100 Grade 1 compliant

■Other functions

・Wide 4.5V~40V input voltage (VIN) range ・Low quiescent current of 35μA (quiescent current) ・Soft start (SS) function for all regulator outputs ・LDO battery short circuit detection ・Open load detection ・Provided in QFN-16 (4mm x 4mm) package ・Provided in wettable flank package
