ISL9237 Datasheet Buck-Boost Narrow VDC Battery Charger

Manufacturer: Renesas

Overview

DATASHEET ISL9237 Buck-Boost Narrow VDC Battery Charger with SMBus Interface and USB OTG FN8723 Rev.5.00 Nov 29, 2017 The ISL9237 is a buck-boost Narrow Output Voltage DC (NVDC) charger utilizing Intersil’s advanced R3™ Technology to provide high light-load efficiency, fast transient response and seamless DCM/CCM transitions for a variety of mobile and industrial applications.

In Charge mode, the ISL9237 takes input power from a wide range of DC power sources (conventional AC/DC charger adapters, USB PD ports, travel adapters, etc.) and safely charges battery packs with up to 3 cells in a series configuration.

ISL9237 supports On-the-Go (OTG) function for 2- and 3-cell battery applications.
