The ISL88733HRTZ-T IC is a high performance mixed-signal PMIC ideal for applications such as portable devices, wearables, and handhelds. The device integrates two smart drivers for buck and boost converters with integrated high-current switches, an advanced analog PWM controller for advanced load management, an integrated linear regulator for system support, two regulated low noise LDOs for core and IO support, a Boost and a Dimmable Boost (OVP) for powering peripherals and an integrated Fuel Gauge for gauge, protection and health management. The device also integrates a power good output, reset, and M-Bus interface.

This PMIC is designed to provide the advanced features and high system performance needed in applications that require extended battery run-times, efficient battery charging and uninterrupted system power. It is capable of supporting up to two cells of Li+ battery, including lithium ion and lithium polymer chemistries. It also features an advanced charge algorithm with Programmable SMBus/INTRQ interface, which allows the programmer to optimize the charging parameters to the specific application. The ISL88733HRTZ-T can be programmed via the SMBus/INTRQ interface to support most of the battery chemistries and provide a wide range of charge currents.

In addition to its robust feature set, the ISL88733HRTZ-T is optimized for high-efficiency operation, with a proprietary power management architecture that reduces power dissipation by over 40%. It also offers reliable protection from over-voltage, under-voltage and over-temperature faults. The device is also very well suited for portable applications and incorporates the latest industry standard short-lead time components for consistent and cost-effective production. The ISL88733HRTZ-T is available in a 2.6 x 2.6 mm package and is fully compliant with RoHS and REACH regulations.

The working principle of the ISL88733HRTZ-T battery charger is based on the control of converter power switches and current sources with both analog and digital control signals. The analog PWM controller controls switch operation and so provides the main power rail for the system load. The two buck converter drivers provide current for the system load and the two boost converter drivers control the charging current for the battery. Finally, the integrated linear regulator provides a linear power rail for the system working from the full or partial powers of the buck and boost regulators. The integrated fuel gauge and SMBus interface provide monitoring and control of the charging process and system power delivery. The SMBus/ INTRQ interface also allows programming of the charge algorithm to further customize charge parameters for each application.

To sum up, the ISL88733HRTZ-T is a high performance PMIC designed specifically for battery powered applications such as portable devices, wearables, and handhelds. It features an advanced charge algorithm with a programmable SMBus/INTRQ interface, reliable protection from over-voltage, under-voltage and over-temperature faults, and is optimized for high-efficiency operation. This device is well suited for portable applications, and is available in a 2.6 x 2.6mm package.
