ISL9241 FN8945 Rev.4.03 Buck-Boost Configurable Battery Charger with SMBus Interface and USB Sep 3, 2020 Power Delivery The ISL9241 is a digitally configurable buck-boost Features battery charger that can support both Narrow Voltage Buck-boost NVDC or hybrid power (turbo boost) Direct Charging (NVDC) and Hybrid Power Buck Boost charger for 2-, 3-, or 4-cell Li-ion batteries using all (HPBB/Bypass) charging and switch between the modes NFET transistors using firmware control. Bypass mode is also supported Input voltage range: 3.9V to 23.4V (no dead zone) using the firmware of the controller, which allows the adapter to provide power directly to the system. The System/battery output voltage: 3.9V to 18.304V ISL9241 provides charging functionality, system bus Bypass mode supported to connect system to adapter regulation, and protection features using only NFETs for tablet, Ultrabook, and notebook platforms. The advanced Autonomous charging option (automatic end of Renesas R3 technology provides a high, light-load charging) efficient Charging mode. The ISL9241 takes input power Adapter current and battery current monitor from a wide range of DC power sources (such as (AMON/BMON) conventional AC/DC charger adapters, USB Type-C PROCHOT open-drain output, IMVP compliant Power ports, and travel adapters) and safely charges battery packs with up to 4-series cell Li-ion batteries. System power monitor PSYS output, IMVP8/9 compliant The system power can be provided from the adapter, battery, or a combination of both. The reconfigurable Internal 8-bit ADC for monitoring key parameters internal registers of the charger allow the use of a smaller USB-C PD Fast Role Swap support and PPS support inductor for the HPBB mode to achieve higher efficiencies across multiple power levels. The ISL9241 Independent compensation pins for forward and can operate with only a battery, only an adapter, or both reverse operation (OTG) modes connected. For Intel IMVP compliant systems, the Supports supplemental power (Intel V active MIN ISL9241 includes System Power monitor (PSYS) protection) functionality, which provides an analog signal Battery Ship mode: IC ultra-low power state representing total platform power. The PSYS output connects to a wide range of IMVP core regulators to Supports JEITA compliance using an NTC provide an IMVP compliant power domain function. The 4x4 32 Ld TQFN package ISL9241 supports reverse buck, boost, or buck-boost operation to the adapter port (OTG mode) from 2- to Applications 4-cell batteries. This allows configurations to support 2- to 4-cell tablets, notebooks, power banks, and any USB-C Power Delivery (PD) output for Programmable USB-C interface portable device requiring batteries Power Supply (PPS) ports.
