Intersil ISL9237HRZ-T

锂离子-10°C ~ 100°C（TA）

Overview

The ISL9237HRZ-T 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-T 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-T supports On-the-Go (OTG) function for 2- and 3-cell battery applications. When OTG function is enabled, the ISL9237HRZ-T 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-T can operate with only a battery, only an adapter or both connected. For Intel IMVP8 compliant systems, the ISL9237HRZ-T 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-T 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.
