Overview
The NCP340MUTBG is a single-channel, high-side power switch manufactured by onsemi. It features an N-channel MOSFET with a maximum continuous output current of 3A and a typical on-resistance of 26 milliohms. The device supports load voltages ranging from 1.8V to 5.5V and operates within a temperature range of -40°C to 85°C. It utilizes a non-inverting input interface and incorporates controlled slew rate functionality to minimize inrush currents. The component is housed in a compact 4-UDFN (1.2x1.6mm) package with a bare pad for thermal dissipation.
Feature Summary
- Integrated high-side N-channel power switch with low on-resistance
- Controlled slew rate capability to manage inrush current during turn-on
- Non-inverting logic interface for straightforward control
- Compact surface-mount packaging optimized for thermal performance
Applications
- Load switching in portable consumer electronics
- Power distribution in embedded systems requiring high-side control
- Inrush current limiting for capacitive loads
- Voltage regulation auxiliary switching circuits
Procurement Notes
Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your assembly requirements. Confirm that the 4-UDFN package dimensions align with your PCB footprint design. Check the latest datasheet for any updates regarding moisture sensitivity level or recommended soldering profiles to ensure reliable manufacturing integration.
Selection Notes
Select this component when a compact, high-side switch is required for loads up to 3A within a 5.5V supply limit. The controlled slew rate feature makes it suitable for applications sensitive to voltage spikes or inrush currents. Ensure the thermal resistance of the 4-UDFN package is adequate for the expected power dissipation in the target application environment.
Part Context
The NCP340 series belongs to onsemi's portfolio of integrated power switches designed for efficient power management. These devices are engineered to replace discrete MOSFET solutions, offering reduced board space and simplified design implementation. The NCP340MUTBG specifically targets applications needing reliable, high-side switching with minimal external components.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains compatible voltage ratings, current capacity, and package dimensions.
