ISL9518HRTZ-T

The ISL9518HRTZ-T is a battery charger specialty IC designed and manufactured by Intersil Corporation. This advanced IC is a power management integrated circuit (PMIC) developed for low power applications and is used to efficiently charge single cell Li-Ion batteries. It is a member of Intersil’s family of Battery Charging Solutions, which help system engineers maximize reliability, efficiency and power savings.

Intersil’s ISL9518HRTZ-T features an embedded 8-bit control core with several advanced features that help system architects complete the design of their next-generation low-power consumer and portable electronic products. The device integrates key components such as a programmable current limit, voltage monitor, and switching controller into a single-chip solution. This advanced IC features a programmable step-down dc-dc conversion, active cell balancer, and discharge feature, which all help provide a complete battery charging solution.

The ISL9518HRTZ-T works in two basic modes. In the Constant Voltage/Constant Current (CC/CV) mode, an external resistor is used to control the charge current. The second mode, the Maximum Power Point Tracking (MPPT) mode, dynamically adjusts the battery charging current according to the load parameters. The device’s programmable current limit and voltage monitor help ensure that the battery charger is only applied to devices which can handle the power.

The ISL9518HRTZ-T provides several benefits to system designers. Its low quiescent current helps extend battery life and improve overall system power efficiency. It also features an adjustable soft-start, which reduces inrush current, and utilizes a fast-charge algorithm which minimizes overall charge time. The device’s power-save feature reduces the battery ripple voltage by decreasing the switch off time, which aids in increasing efficiency and battery life.

The ISL9518HRTZ-T is an ideal solution for low power applications and is designed for use in portable and consumer electronic devices. It is well-suited for cell phones, digital cameras, PDAs, and other battery-powered applications. The device is available in an 8-pin TQFN package, which helps simplify board layout and reduce the solution’s footprint. In addition, the device is RoHS and lead-free, making it compliant with industry standards.

Intersil’s ISL9518HRTZ-T is an innovative PMIC designed for low-power applications. It helps system designers save energy and maximize performance, while bringing their systems to the next level of power efficiency. With its advanced control core and integrated features, the ISL9518HRTZ-T makes designing a battery charger simple and easy.
