NCP1094MNG

Overview

The NCP1094MNG is a Hot Swap Voltage Controller from onsemi, designed for Power over Ethernet (PoE) and LAN solutions. It operates within an input voltage range of 0 V to 57 V and supports a maximum output current of 500 mA. The device features a low operating supply current of 600 uA and includes power failure detection capabilities. It is housed in a DFN-10 surface-mount package and functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated hot swap control for safe insertion and removal of circuits under load
• Built-in power failure detection mechanism for system protection
• Optimized for low quiescent current operation in PoE applications

Applications

• Power over Ethernet (PoE) interface circuits
• LAN solution power management
• Hot swap controller implementations

Procurement Notes

Verify the specific suffix of the ordered part number against official documentation, as variations may exist. Confirm that the component meets required environmental standards such as RoHS compliance before integration. Check for any active Product Change Notifications or End-of-Life notices from the manufacturer to ensure long-term availability and supply chain stability for the project lifecycle.

Selection Notes

Select this component when designing systems requiring controlled power sequencing for hot-pluggable interfaces. Ensure the application input voltage does not exceed the 57 V maximum rating. Consider the DFN-10 package constraints for thermal management and PCB layout. Verify that the 500 mA current limit aligns with the downstream load requirements and fault protection thresholds.

Part Context

This device belongs to the NCP1094 series of power management ICs focused on PoE and LAN applications. It serves as a specialized controller for managing power delivery during connection events. The series is categorized under PMIC solutions, distinct from general-purpose regulators or gate drivers offered by the manufacturer.
