The ICL7673CBAZA is a PMIC, OR Controller, and ideal diode integrated circuit (IC) for use in a variety of applications. It offers high flexibility, reduced component count, higher power density, and improved energy efficiency.

The PMIC and OR Controller functions of the ICL7673CBAZA allows it to be used as a central power system component, providing efficient control of multiple supplies, while the ideal diode function, which acts like a diode and gives a voltage drop of less than one millivolt, can be used to provide reliable protection of voltage paths from reverse polarity and short circuit loads.

The ICL7673CBAZA is capable of providing multiple capacitor sources connected in parallel, a peak current mode control for fast transient response, and voltage tracking for synchronizing multiple secondary supplies to reduce all the away and simplify board layout, as well as many options for enabling and disabling each output. It also offers wide voltage ranges, up to 24 volts, and current ranges up to 5 amps.

The ICL7673CBAZA’s working principle is based on a regulated steady-state converter circuit, where the converter switches appropriately when the converter output voltage or output current falls below or rises above a predetermined level. This principle ensures a continuous and stable output voltage and current, despite input ripple, transient conditions, and other sources of instability.

The ICL7673CBAZA is an ideal choice for a range of applications requiring selective levels of power management, ranging from controlling multiple supplies for automotive and industrial equipment, to point-of-sale systems, serial interface controllers, air conditioning controllers, and LCD displays.

It can be used to supply power for active device biasing and sensor power, eliminating the need for dedicated bias regulators and handheld motors, and it can also be used as an OR controller in flat panel displays, supplying precise voltage levels and increasing overall efficiency.

In addition, the ICL7673CBAZA is capable of providing multiple low current, low voltage outputs with tight tolerances and fast response times, thus reducing power consumption and providing power savings.

In summary, the ICL7673CBAZA offers high flexibility, reduced component count, higher power density and improved energy efficiency, making it an ideal choice for many power management applications. Its PMIC and OR Controller functions allow it to be used as a single, central power system component, while its ideal diode function provides reliable protection of voltage paths from reverse polarity and short circuit loads. Additionally, its peak current mode control and voltage tracking features ensure a stable output voltage and current despite input ripple, transient conditions, and other sources of instability.
