LP3923TL/NOPB is a power management integrated circuit with specialized features from Texas Instruments. It is most often used in digital still cameras and point-and-shoot digital cameras. It is also used in some cell phones, personal media players and other digital devices, and is in some industrial applications.

LP3923TL/NOPB is often referred to as a power management integrated circuit (PMIC). It consists of a power management unit (PMU), a power management system (PMS), an external component, and some additional circuitry. The PMU is responsible for controlling the power supply and can control the power-down sequence when the device is in standby, as well as the power-up sequence when the device is powered up. The PMS provides the data interface between the device and the PMIC. The external component is the IC itself, which contains the logic and processing required to power the device and control the power-down and power-up sequences. The additional circuitry includes the input and output converters, the voltage supervisors, the voltage regulators and other components.

LP3923TL/NOPB is an advanced power management IC that offers the flexibility to customize the power management, increasing the system efficiency and reliability. It can monitor, control and protect the power management functions of various devices and systems. The IC incorporates a low-power integrated Power on Reset (POR) function, high-frequency start-up/shut-down sequencing, and low-noise reference voltage outputs, making it suitable for battery-operated applications.

The LP3923TL/NOPB offers several integrated protection features to protect the device in a power system. These include under-voltage lockout (UVLO), over-current protection (OCP), output voltage and current limit and current-sense limit. The IC can also be configured to provide logic output signals such as power good and system ready. Additionally, it offers intelligent power saving features such as power sequencing, power saving interval adjustment and advanced current sensing. The IC also includes several pin-configurable options for controlling shutdown, bleeder resistor, programmable current limit and analog control.

LP3923TL/NOPB is a highly integrated, easy-to-use, low-cost PMIC that is optimized for use in digital still cameras, point-and-shoot digital cameras, smart phones, personal media players and other power management applications. It provides system designers with a wide range of flexibility to customize the power management of their devices, resulting in improved system reliability and performance. Its advanced power management features, integrated protection circuits and well-documented documentation make LP3923TL/NOPB an ideal choice for power management applications.
