The NCP6153MNTWG is a high current integrated power management solution designed specifically to allow designers greater flexibility in producing highly efficient, low standby current and cost-effective applications. This power management IC features Power over Ethernet (PoE), buck, and boost voltage regulation, as well as comprehensive load monitoring and system reset generation capabilities, along with general power management control. The NCP6153MNTWG is ideally suited for high-current PoE applications with both low and high voltage inputs, such as industrial and consumer applications including DC-DC power supplies and LED lighting.

This device is part of Power Management ICs (PMICs) which are integrated circuits used to regulate power in modern-day electronic systems. As a Voltage Regulator, PMICs are designed to manage the flow of power efficiently and safely by regulating the output voltage/current as mandated by the device operating conditions. Under the Special Purpose section, this encompasses voltage regulators designed for a specific application or purpose. Voltage regulators in this category are usually more tailored and provide more specific functions, more efficient power management, and better overall operation.

The NCP6153MNTWG includes a Power over Ethernet (PoE) interface, enabling support for various IEEE802.3-compliant PD applications. This allows for an automatic detection of connected loads, including signaling and classification. The PoE controller is optimized for many types of PDs found in active Ethernet and Power sourcing equipment applications, such as Power-over-Ethernet (PoE) ports. It includes input detection, classification, and overload protection circuitry, as well as control of supply enable pins.

The buck and boost voltage regulation sections of the NCP6153MNTWG provide 100mA current capability for standard buck or boost output configurations. The buck and boost can be used independently to provide two isolated outputs at voltages between 0.9V and 5.5V, allowing for greater flexibility and cost savings due to fewer external components. The threshold voltage of the boost provides the capability to regulate the output voltage from any power source, including AC-DC adapters, batteries, and more.

The comprehensive load monitoring and system reset generation section provide flexible, user-configurable power management and reset options. The NCP6153MNTWG enables control of supply enable pins and allows for multiple power rails in the system. Load monitoring provides voltage and current monitoring of individual supplies and will assert a system reset if the system load is overloaded or if the output voltage drops below a pre-set threshold value. The system reset output can be configured with either pulse or latch behavior.

In summary, the NCP6153MNTWG an integrated high current power management solution specifically designed to provide designers with greater flexibility in producing highly efficient, low-standby power, and cost-effective applications. This device provides PoE, buck, and boost voltage regulation, comprehensive load monitoring and system reset generation capabilities, making it suitable for use in industrial and consumer applications including DC-DC power supplies and LED lighting.
