PI5USB1457ZAEX is a device developed by Pericom Semiconductor for the PMIC - Power Distribution Switches, Load Drivers classification. It is a specialized and highly integrated IC for generating two SMBus-controlled, DC-to-AC-converting switching outputs with individually adjustable peak current and dynamic reset. The device is designed for applications with strict power conservation and wide input voltage range from 4.5V to 60V. It features fast turn-on/off and overvoltage protection.

The device has four outputs: two primary outputs, two auxiliary outputs and four levels of protection. The primary outputs are ideal for powering devices with extremely low quiescent current. The two primary outputs are independently programmable with adjustable peak current, combined with advanced internal circuitry for dynamic item reset. The two auxiliary outputs can provide their own power for additional devices such as through-hole relay pins instead of drawing from the main power source.

The device also provides four levels of protection including overvoltage protection, overcurrent protection, and overheat protection. Overvoltage protection prevents the system from back-driving power into the output, while overcurrent protection shuts off the output when it senses too much load. Overheat protection helps protect the system from excessive power constraints or other occasions where the device may get too hot.

PI5USB1457ZAEX enables new system configurations and designs with great thermal efficiency and improved cost, while maintaining a high level of protection. It requires less board space, reduces the number of components, and is compatible with existing power architectures such as PMBus. The device provides minimal system overhead and is optimized for fast turn-on/off times.

The device is designed for applications that require wide range of input voltage which is from 4.5V to 60V. It can also be used for controlling DC-DC converters, managing power shut downs and various other applications in the automotive and industrial automation domains. It can be used to provide power to multiple devices with peak current and dynamic reset.
