Renesas Introduces USB PD EPR Solution Featuring Type-C Port Controller and Buck-Boost Battery Charger: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. New Solution Offers Superior Efficiency and Safety Features for Power Tools, Portable Vacuums, Lawn Mowers, Two-Wheelers, and More

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 best 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.

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.
