Overview
The NCP380HMU05AATBG is a high-side power distribution switch from onsemi, designed for applications with large capacitive loads and potential short circuits. It integrates a P-channel MOSFET with a maximum on-resistance of 75 mΩ in a uDFN-6 package. The device features a fixed current limit of 500 mA, operating within a supply voltage range of 2.5 V to 5.5 V. It includes controlled slew rates to minimize current ringing and provides status flagging for overcurrent, reverse voltage, or thermal conditions.
Feature Summary
- Integrates a P-channel MOSFET with low on-resistance for efficient power distribution
- Features fixed current limiting to protect against overload and short circuit conditions
- Includes controlled slew rate capability to reduce switching noise and current ringing
- Provides internal protection mechanisms including reverse voltage detection and thermal shutdown
Applications
- Power distribution in systems with large capacitive loads
- Short circuit protection in electronic circuits
- High-side switching applications requiring current limiting
- Systems needing controlled turn-on/off slew rates
Procurement Notes
Verify the specific part number NCP380HMU05AATBG against official onsemi documentation to confirm availability and specifications. Check for any product change notices (PCNs) related to manufacturing or packaging updates. Ensure compatibility with your system's voltage and current requirements before procurement.
Selection Notes
Select this component when a fixed 500 mA current limit is required for high-side switching. Consider the uDFN-6 package size and the 75 mΩ on-resistance for power dissipation calculations. Evaluate the need for controlled slew rates to manage inrush currents in capacitive load scenarios.
Part Context
The NCP380 series comprises high-side power switches with various current limit options. This specific model offers a fixed 500 mA limit, distinguishing it from adjustable variants like the NCP380HMUAJAATBG. It belongs to the broader family of power management ICs designed for robust load protection.
Replacement Considerations
For direct replacements with identical fixed current limits, consider other NCP380 models with similar specifications, such as NCP380HMU10AATBG or NCP380HMU15AATBG, ensuring the current limit matches application needs. Verify pinout and package compatibility.
