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, a well-known power semiconductor and chip supplier integrating design, development, production and global sales (AOS, Nasdaq: AOSL), is now launching a new P MOS transistor--AONR21357, which is improved by The P pre-processed implementation achieves lossless and more reliable startup, standard DFN 3*3 package, BVDss=-30V, VGS=-25V, Rdson=12.3mohm @ VGS=-4.5V, useful for notebook power adapters and Ideal for 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 transistor, excellent performance such as ultra-low Miller platform and low-loss switching characteristics ensure its reliability and safe working area, so that R & D engineers Able to implement simple designs with P MOS transistors” Rack Tsai, product director of low-voltage MOSFETs at AOS.

Technical advantages:

This new product line can provide a variety of different RDSON and various packaged products.
