The HIP1011ACBZA chip is a PMIC – Hot Swap Controller designed for enhanced reliability and performance in hot-swap applications. The chip provides a wide range of features and benefits, making it an ideal solution for hot-swap designs.

The primary function of the HOT1011ACBZA is to manage current through a hot-swap circuit. It is an SCR that detects the inrush current and limits it to a specified maximum. In order to guarantee reliable control and to minimize system power losses, the HOT1011ACBZA works in a sequential procedure.

The first step is to enable the HOT1011ACBZA by pulling a trim pin high. This pin also enables the DC bias circuit which provides the supply voltage for the HOT1011ACBZA. The HOT1011ACBZA will then apply power to the hot-swap circuit. The circuit is held in this condition until the actual current is detected by the HOT1011ACBZA. Once the designated current limit has been reached, the HOT1011ACBZA reduces the current by using its unique current-limiting control circuit.

When working with the HOT1011ACBZA, it is important to note that the recommended maximum current must be less than 16A. Over-rating the maximum current will cause unstable operation and potentially catastrophic failure. The HOT1011ACBZA also supports fast-recovering zero-charging mode to eliminate any chance of reverse-current inrush.

Additional features of the HOT1011ACBZA include undervoltage and overvoltage protection, thermal protection, charge-pumping mechanism, and the ability to interface directly with a processor. The HOT1011ACBZA is designed to use a minimum number of external parts, resulting in a reduction in system costs.

The HOT1011ACBZA is an ideal solution for hot-swap applications that require fast and reliable current limiting, strong protection, and optimized system design. It is an ideal choice for systems that need to drive a switching power supply, or support high current DC loads. Thanks to its advanced features and reliable protection, the HOT1011ACBZA is one of the most advanced PMICs for hot-swap applications.
