Overview
The NCP81418MNTXG is a hot swap slave-only smart fuse from onsemi, designed for high-current server applications. It integrates an N-channel MOSFET with a thermal management controller in a 32-LQFN (5x5 mm) package. The device supports an input voltage range of 5V to 18V and delivers up to 80A peak output current. Key electrical parameters include a maximum on-resistance of 1.3 mΩ and a typical value of 650 mΩ. It operates within a temperature range of -40°C to +125°C and features adjustable current limiting, over-temperature protection, and overvoltage protection.
Feature Summary
- Integrates low RDS(on) NMOS FET with hot swap controller for simplified design
- Supports TWI communication interface for master-slave coordination
- Provides programmable overcurrent protection levels with adjustable debounce times
- Features controlled slew rate and status flag outputs for system monitoring
Applications
- High-current 12V hot swap applications in servers
- Power distribution units requiring smart fuse functionality
- Systems utilizing master-slave hot swap architectures
Procurement Notes
Verify the specific suffix 'MNTXG' against the manufacturer's official datasheet to confirm the tape and reel packaging configuration. Ensure compatibility with TWI interfaces if used in a master-slave setup. Check RoHS compliance status as indicated in the latest product documentation before finalizing procurement specifications.
Selection Notes
Select this component when a dedicated slave-side hot swap solution is required alongside a master controller like the NCP81428. Consider the 32-LQFN package size for space-constrained designs. Evaluate the 80A peak current capability against transient load requirements. Verify that the 5V to 18V input range matches the system power rails.
Part Context
This part belongs to the NCP81418 series of smart fuses. It is specifically engineered as a slave device, meaning it relies on external control signals or a master IC for certain operational modes. It complements other power management solutions by providing robust protection and precise current monitoring in high-density power distribution networks.
