Intersil ISL9237HRZ

Литий-ионный-10°C ~ 100°C (TA)

Overview

The ISL9237HRZ 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 ISL9237HRZ 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.ISL9237HRZ supports On-the-Go (OTG) function for 2- and 3-cell battery applications. When OTG function is enabled, the ISL9237HRZ operates in the reverse Buck mode to provide 5V at the USB port.As a NVDC topology charger, it also regulates the system output to a narrow DC range for stable system bus voltage. The system power can be provided from the adapter, battery or a combination of both. The ISL9237HRZ can operate with only a battery, only an adapter or both connected. For Intel IMVP8 compliant systems, the ISL9237HRZ includes PSYS functionality, which provides an analog signal representing total platform power. The PSYS output will connect to a wide range of Intersil IMVP8 core regulators to provide an IMVP8 compliant power domain function.The ISL9237HRZ has serial communication via SMBus/I2C that allows programming of many critical parameters to deliver a customized solution. These programming parameters include, but are not limited to: Adapter current limit, charger current limit, system voltage setting and trickle charging current limit.
