These two new ICs combine to provide a premier Extended Power Range (EPR) USB Power Delivery (PD) solution.
Renesas offers a comprehensive range of products including turnkey solutions for various applications and helps customers shorten their time-to-market with an extensive development environment and pre-certified USB-IF reference designs.
The RAA489118 functions as either a battery charger supporting two to seven battery cells in series or as a voltage regulator supporting 30V input and 30V output. It employs Renesas’ patented R3 (Robust Ripple Regulator) technology, which combines the features of fixed-frequency and hysteretic Pulse-Width Modulation (PWM) technologies. R3 modulation technology delivers acoustic noise-free operation, fast dynamic response, and best-in-class light-load efficiency for longer battery life.
The RAA489118 includes an SMBus (System Management Bus) interface that is widely employed in power tools, home appliances and light industrial products.
The SMBus interface, combined with the buck-boost and bidirectional features, allows the RAA489118 to work seamlessly with the RAA489400 and other components in USB-C PD implementations. Its input and output voltage levels also match mainstream solar power voltage levels, making it an ideal fit for solar portable power station applications.
The RAA489400 port controller supports USB-PD VBUS power up to 48V/5A and features an integrated PHY, both Sink and Source Power Path Gate Drivers with external NFETs, short-circuit protection, VBUS discharge, a VCONN MUX and dead battery support.
