The ADP191ACBZ-R7 is an integrated circuit composed of a high-side power distribution switch, load drivers, and other components on a single chip. In applications where power must be distributed to multiple load circuits, and load current must be regulated and protected, the ADP191ACBZ-R7 is an ideal solution. The circuit allows for a separate power source to be used to drive the loadcurrents, while simultaneously protecting and isolating the source from the loads.

The ADP191ACBZ-R7 allows for the control of each load separately, and can support up to three different AC or DC loads. The circuit has an adjustableoutput voltage range of 0.5V to 7V, with a current output capability up to 10A. The input voltage is internally limited to 85V.

The ADP191ACBZ-R7 has several built-in protection and monitoring features, including over-current and over-temperature protection capabilities. This allows the application to protect its own components, while simultaneously providing a safe operation. The load current can be monitored, with a threshold set on the current that can be drawn from the load.

The ADP191ACBZ-R7 utilizes a two-level system to control the current and prevent overloads. The two-level system features a highside switch, which is connected directly to the supply power source, and two separate current controls whose output is connected to the load itself. By controlling the current at the high-side switch, the load current is regulated and protected. The two-level system is also used to protect the power source from overloads.

Furthermore, the ADP191ACBZ-R7 is equipped with a fault detection circuit. This circuit monitors the load current and can detect faults in the connection between the power source and the load circuits. The detection circuit triggers a fault alarm when it senses an overload, short circuit, or excessive current.

The ADP191ACBZ-R7 provides a robust, easy-to-use power distribution solution for multiple load circuits. Its built-in protection features make it well-suited for various applications, ranging from consumer electronics to industrial applications. Its small size and ease of integration make it particularly attractive for use in portable and battery powered devices.
