PMIC - Hot Swap Controllers

The HIP1011BCBZA application is a hot swap controller for System Power Management. It can provide various management functions for hot plugging of system power supplies and offers a reliable, quick, smooth and low-power solution for modern hot swappable systems. It is designed by using advanced CMOS process technology, and provides an ultra-low power solution and high degree of integration.

This hot swap controller can be used to implement the transition between powered-off and powered-on hot swappable conditions, providing a good working environment and minimizing transient current during the transition. It features an onboard low-voltage detector (LVD) to prevent system damage due to undervoltage or other faults, as well as a high-voltage shutoff (HVSO) circuit that ensures the implementation of an orderly shutdown under high-voltage conditions. Onboard temperature detection can also be used to monitor device temperature and protect the overall system from overheating.

The working principle of the HIP1011BCBZA application is to detect the voltage value of the power source, and then control the powering on and powering off protection of the system according to the preset voltage value. It also monitors the temperature of the board and provides a high degree of reliability by automatically controlling the shutoff of the system when the temperature is too high.

When the power supply is connected and the voltage reaches the preset threshold, the controller will enable the hot plugging sequence and provide power to the system. During normal operation, the controller will keep monitoring the voltage value and temperature of the system and automatically shut off the system if any faults occur. If there is an undervoltage condition, the controller will shut off the system and be ready for the next power on cycle.

The HIP1011BCBZA provides an efficient and guarded power-on sequence, protecting system boards from transient current surges caused by memory refresh or other system components. When the power supply reaches the preset voltage, the voltage regulator will see this as the activation signal, and then quickly reduce the output current to a safe value.

In summary, the HIP1011BCBZA hot swap controller provides a variety of power management solutions for hot swappable systems, making power managementfast, reliable, and low power. It offers temperature monitoring and control, as well as overvoltage/undervoltage protection, helping to ensure the safe and efficient operation of a hot swappable system.
