PMIC - Hot Swap Controllers

The ADM1070ARTZ-REEL is a hot swap controller integrated circuit (IC) which is commonly used in many applications. This device offers a solution to protecting sensitive electronics from overcurrent, overvoltage and thermal damage. The device offers protection with low “on resistance” and wide operating range, providing improved power management and system reliability. The ADM1070ARTZ-REEL has a wide range of features like integrated current sensing and overvoltage protections, as well as thermal protection and auto burst mode.

Applications

The ADM1070ARTZ-REEL is typically used in power management applications such as systems with hot swap controllers, DC-DC converters, multi-rail power supplies, and power solutions for server, storage and telecommunication systems. It is also used for replacing fuses and protecting circuits from thermal runaway and overvoltage. The device is designed to provide overvoltage, overcurrent and thermal protection for systems that require integrated power management capabilities in a fast, cost-effective environment. This IC also provides user-adjustable trip points and timing for current, voltage, and thermal limits while achieving excellent power efficiency.

Working principle

The ADM1070ARTZ-REEL works through sensing the input voltage, current and temperature that lies within the allowable range. If the device detects any parameter that is outside of the preset range, the device will activate its protection mechanism. If the overvoltage threshold is exceeded, it will latch off until the voltage is reduced to a safe level. If the current limit is exceeded, it will reduce the output voltage by means of a non-latching linear dropout until the current level is reduced. Finally, if the temperature level is exceeded, the device will latch off until the temperature has sufficiently reduced.The ADM1070ARTZ-REEL offers adjustable current and temperature sensing options using hysteresis, which allows the user to adjust the upper and lower current and temperature thresholds to optimize performance. The device also has thermal protection with adjustable hysteresis, which helps to keep the device cool and reduce power dissipation.

Conclusion

The ADM1070ARTZ-REEL is an integrated and cost-effective hot swap controller IC that is used in power management applications to efficiently manage system power and protect hardware from overvoltage, overcurrent and thermal damages. The device offers a wide range of features and adjustable parameters so that it can be tailored to the needs of each application. This IC also offers superior power management efficiency and system reliability.
