AOS released the latest P-MOS transistor for USB PD load switch

Wide input voltage, versatile and robust USB PD load switch solution

A few days ago, AOS (AOS, NASDAQ: AOSL), a well-known power semiconductor and chip supplier integrating design, development, production and global sales, is now launching a new P MOS transistor--AONR21357 , Loss achieved and more reliable start-up with improved P pre-process, standard DFN 3*3 package, BVDss=-30V, VGS=-25V, Rdson=12.3mohm @ VGS=-4.5V, useful notebook Ideal for power adapters and battery load switches.

USB Typc-C has become the mainstream interface for PCs and mobile phones, so the USB-PD standard can be widely implemented because it covers the different power transmission needs of a variety of portable devices. The load switch circuit is used to control the on/off of the power busbar, the AONR21357 is used for the load switch for a wide range of input and output voltages, and its robustness and high reliability are suitable for various operating conditions. AOS' improved P-Series technology should be robust enough to operate in linear mode, and the ultra-low Miller platform (<3.5V) can cover mainstream USB-PD voltages.

"AONR21357 fully meets the application requirements of -30VDS/-25VGS P series MOS transistors, excellent performance such as ultra-low Miller platform and low-loss switching characteristics ensure its reliability and safe working area, thus Enables R&D engineers to implement simple designs using P MOS transistors,” said Rack Tsai, product director of low-voltage MOSFETs at AOS.

Technical advantages:

This new product line offers a variety of different RDSONs and packages.
