Introduction:

P9023-2AHGI8 is a specialized power management integrated circuit (PMIC) from Toshiba. It is designed to support a wide range of applications such as SD/MMC card controllers, hard disk controllers, USB host/OTG controllers, image processors, and other digital media devices. It is also suitable for low-power portable systems, such as digital video cameras, gaming miniature consoles and PDAs. The device integrates a single-channel controller, a step-down converter, a Low Dropout (LDO) voltage regulator, error protection circuits and other functions into a single package.

Application field:

The P9023-2AHGI8’s unparallel features make it suitable for a broad range of applications such as electronic equipment and computer systems. The device’s single-channel controller offers up to 2.6 Amps of current output, enabling it to support heavy-current applications. Its low-power and low quiescent current modes make it ideal for high-sensitivity applications. Additionally, the device supports multiple protection functions including internal protection from overheating and overcurrent fault, overvoltage protection and output control (OCP). The P9023-2AHGI8 also features a high efficiency step-down converter for providing supply voltage for up to 1A of current. The adjustable output voltage of the converter makes it suitable for powering any digital logic circuits. Moreover, it is able to provide a very low operating temperature due to its minimal current consumption. The device’s error protection circuits include load disconnect, sampling and hold, short-circuit protection, and many other features that protect the device from various faults such as overloads, overvoltage, and overcurrent. The device also includes an LDO voltage regulator which is able to deliver 0.8 to 5V at 1A and enable the user to adjust the output voltage for different applications.

Working Principle:

The P9023-2AHGI8 works by converting a low-voltage DC input into a high-voltage DC output. It accomplishes this process by using the single-channel controller. The controller controls a switch that is connected in series with a high-frequency transformer. When the switch is turned on, current flows through the transformer’s primary winding, and a magnetic field is generated. The transformer’s secondary winding then produces a step-up voltage on its output.The converted voltage is regulated by the LDO regulator, which features low dropout and quite low power emissions. The adjustable output voltage of the regulator allows for higher voltage range for power supply. The device\'s error protection circuits kick into play when an unexpected event, such as overcurrent, occurs. The overcurrent event will trigger the OCP and the load will be disconnected in order to protect other parts of the circuit.In addition, P9023-2AHGI8 features a Thermal Shutdown (TSD) circuit which provides thermal protection at the output by monitoring the die temperature. When the die temperature reaches a predetermined high temperature, the TSD circuit will shut down the output, providing additional protection.

Conclusion:

The P9023-2AHGI8 Power Management Integrated Circuit is specifically designed to provide efficient, reliable power management for a wide range of applications. It combines a single-channel controller, a step-down converter, a Low Dropout (LDO) voltage regulator, and a variety of error protection circuits into a single package. The device also features a high efficiency step-down converter that can provide up to 1A of current, as well as a low-power and low-quiescent current modes to support light-load applications. Additionally, the device includes several protection features such as overcurrent, overvoltage, and overload protection, as well as a Thermal Shutdown circuit for providing additional protection.
