Renesas introduces extended power USB chipset
Renesas has introduced the RAA489118 buck-boost battery charger and the RAA489400 USB Type-C port controller. The two new ICs combine to provide a premier Extended Power Range (EPR) USB Power Delivery (PD) solution.
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 the firm says combines the best features of fixed-frequency and hysteretic 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. It 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.
“Renesas has been a worldwide leader in battery charging for many years based on advanced technology, adaptability, and exceptional value,” said Chris Allexandre, SVP and general manager of Power at Renesas. “The RAA489118 and RAA489400 bring those strengths along with Renesas’ strong legacy of safety and reliability to new applications such as power tools and light industrial products. We expect to see strong demand from customers across multiple markets.”
The RAA489118 comes in a 4×4 mm 32-lead TQFN package, and the RAA489400 is packaged in a 32-Ld 3x5 mm FCQFN. Both products are available today from Renesas. Design support and tools, including VIDWriter configuration tools and battery charger GUI software to configure designs, are also available.
