ISL6252HRZ-T

The ISL6252HRZ-T is a feature-rich, integrated power management IC (PMIC) designed for battery charging, fuel gauge, power path and system power management in applications like smartphones, tablets and notebooks.

ISL6252HRZ-T can help reduce system power and overall system size, while delivering optimal performance. At the heart of the chip is Intersil’s OTP (One-Time Programmable) technology, which provides run-time flexibility and offers a variety of features that support multiple system functions ranging from Li-Ion battery charging and power path management, to system power-up sequencing, fault protection, LED current regulation, display bias regulation and system wake up.

In the field of PMIC-Battery Chargers, ISL6252HRZ-T is an ideal device for those applications that require high efficiency, accuracy and reliable power management, such as smartphones and tablets. With the ability to manage up to 5.5V of input voltage and regulate up to 2A current for load, this device is able to meet the demands of any system powered by Li-Ion batteries.

The ISL6252HRZ-T is designed to provide high accuracy, efficient and reliable charging of Li-Ion batteries. It features a 1-cell, Li-Ion battery charger with an integrated DC-DC Power Path, a dedicated low dropout (LDO) regulator, an over-voltage protection (OVP) circuit, a fault detection circuit and a system power-up sequencing controller.

The DC-DC Power Path allows the device to supply power to the system load while also providing charging current to the battery. The integrated LDO provides a regulated output that is ideal for powering up digital logic, display bias and similar functions. Additionally, the OVP circuit protects the battery from overcharge conditions by monitoring the battery voltage and shutting down the charging current if the voltage rises above a certain threshold.

The fault detection circuit monitors the current and voltage of the system for any abnormal conditions and sends an IC signal indicating an error or warning condition if any occurs. This allows for better system management as the IC can detect common faults such as open circuit or overcurrent before potential damage is caused to system components.

The system power-up sequencing controller in the ISL6252HRZ-T uses power signal commands to the regulator section to properly control and sequence the system startup while preventing damage to system components. This feature is particularly useful in applications where the power-up sequence needs to be tightly monitored and controlled.

Overall, Intersil’s ISL6252HRZ-T is a comprehensive power management IC designed to provide accurate, efficient, and reliable power management for a wide variety of applications. With the integrated DC-DC power path, LDO regulator, fault detection circuit, and power up sequencing controller, this device is able to provide a robust and reliable power management solution for any system powered by Li-Ion batteries.
