ISL88041IBZ-T

The ISL88041IBZ-T is a supervisor specifically designed and optimized to provide the power supply sequencing requirements necessary for the Intel architecture processor and chipset. It features a 4.2V to 4.3V adjustable supply voltage generation, 4 power sequencing steps and a single step sequencing of 3.3V. The supervisor is designed to work along Silicon Labs precision voltage detectors, allowing complete system level protection and a few combined functions in a very small package.

The ISL88041IBZ-T supervisor can be used in a variety of applications where either power sequencing is needed or an integrated system power control function is required. It can be used for many Intel® microprocessor-based systems, such as desktop computers, embedded systems and modular communications systems. It can replace almost any other power supervisor or multiple discrete components for enhanced system level protection.

Working Principle of ISL88041IBZ-T

The ISL88041IBZ-T has 4 power sequencing steps and 3.3V single step sequencing with each step having a separate adjustable delay. This supervisor provides the proper power-up and power-down sequencing of the processor\'s core Voltage Regulator Modules (VRMs) and voltage regulator. This provides system level protection against over-voltage and power failures. The supervisor also ensures that the cache, BIOS and other mainboard components are powered on and off sequentially.

The ISL88041IBZ-T also includes over-current protection, as well as over-voltage protection, thermal shutdown and under-voltage protection. This supervisor will also monitor the system\'s power supply voltages and will shut down the system to prevent over-voltage conditions that can damage components. The supervisor\'s voltage monitors are adjustable, reliable and have a wide operating temperature range.

The ISL88041IBZ-T supervisor also features advanced features such as power-fail monitoring, software reset and watchdog timer with precision voltage detect and active high reset. This helps to ensure that the processor is running well and is providing the correct voltage to the other components in the system. This prevents system crashes and prolongs the life of the processor and other components.

The ISL88041IBZ-T can also be used in other applications such as Industrial and Automotive. In industrial applications, the ISL88041IBZ-T can be used for protection against voltage transients caused by the drive of motors as well as power control for USB and/or Ethernet communication systems. In Automotive applications, the ISL88041IBZ-T can provide power sequencing for engines, headlights, and ABS systems.

The ISL88041IBZ-T can also be used for Battery Backup Applications. It can provide power supply sequencing and power-fail monitoring for battery backup systems. Its built-in low-voltage detectors can detect low battery voltages and initiate a power-fail sequence with an adjustable delay.

The ISL88041IBZ-T is a highly versatile device designed to bring advanced power supply sequence control and monitoring in a small and efficient package. This supervisor can help designers improve system level protection and increase system reliability.
