ISL6119HIBZA-T

The ISL6119HIBZA-T, manufactured by Intersil, is a Hot Swap Controller, a type of Power Management Integrated Circuit (PMIC) designed to act as an autonomous, self-containing management and safety device. This Hot Swap Controller, in particular, provides versatile hot swap circuit protection and can drive external MOSFETs or N-channel IGBTs to implement any power supply topology. As an ideal addition to Intersil’s industry-leading power solution portfolio, the ISL6119HIBZA-T is able to supply a total output current 150A.

The ISL6119HIBZA-T features multiple user-configurable parameters and gives designers the flexibility to set voltage and current limits for each load for optimized applications. Several features such as N-Channel MOSFET/IGBT driver, overcurrent/overvoltage protection, watchdog timer, and line fault detection, along with logic-level output voltage, provide a wide range of protective, control and reporting options. Its various Overvoltage Target and Fault Time-out Period settings, along with the programmable Sequence Delay Timer enables a more customized protection strategy.

The ISL6119HIBZA-T provides four channel confi gurations allowing up to 4 devices to be controlled by a single controller. It can be used to provide either four independent DC/DC channels or multi-phase power with up to six phases. The channels are actually 2-phase and 2-phase can be combined where required and all six phases can be sequenced by one controller. Additionally, each channel has short-to-battery protection, short-circuit protection, and foldback/droop current sharing. The output voltage, rise/fall times, overvoltage/undervoltage tolerances, and overcurrent foldback all can be precisely controlled, eliminating the need for external circuitry.

The ISL6119HIBZA-T also features thermal feedback and ramp compensation options, making it a great choice for applications that require high reliability and precision. The thermal feedback option ensures the device remains below a certain specified temperature for maximum reliability and performance. The ramp compensation feature delivers a more constant load current despite variations in the input voltage and other environmental conditions. All this, of course, is accompanied by overload protection, allowing the device to continue performing without experiencing any damage.

The ISL6119HIBZA-T employs the power converter monitoring and protection feature found in the most advanced PMICs. This feature enables the converter to monitor, protect and report its own operating conditions from temperature, power and voltage. The device also provides an output port adapter for automatic load sequencing. This feature can be used to detect various conditions such as a power shortfall, driver failure, overvoltage or overcurrent conditions and circulate control signals between the various power supplies to ensure safe and optimal operation.

In conclusion, the ISL6119HIBZA-T is a powerful and very reliable Hot Swap Controller, part of Intersil’s industry-leading power solution portfolio. Serving a wide range of applications, the device allows users to precisely control various parameters such as output voltage, rise/fall times, overvoltage/undervoltage tolerances, and even temperature, making sure the supplied power source is always safe and efficient. Due to its exceptional design and remarkable features, the ISL6119HIBZA-T can serve as a perfect solution for any power supply system in need of elaborate protection.
