NCV380HMUAJAATBG

Overview

The NCV380HMUAJAATBG is an automotive-grade high-side power distribution switch featuring a single P-channel MOSFET with a maximum on-resistance of 110 mOhms. It supports an output current range from 500 mA to 2.1 A, adjustable via an external resistor. The device operates within a load voltage range of 2.5 V to 5.5 V and includes controlled slew rates with a maximum rise time of 4 ms and fall time of 3 ms. It provides overcurrent protection, reverse voltage blocking, and a status flag output, functioning reliably across temperatures from -40°C to +85°C.

Feature Summary

• Integrates a P-channel MOSFET for high-side power switching with adjustable current limiting capabilities.
• Features controlled slew rate management to minimize current ringing during switching events.
• Includes internal reverse voltage detection to protect upstream components when output exceeds input.
• Provides a logic flag output indicating fault conditions such as overcurrent or thermal stress.

Applications

• Automotive electronic control units requiring robust high-side switching
• Capacitive load distribution in vehicle infotainment systems
• Short-circuit protected power routing for automotive sensors

Procurement Notes

Verify the specific suffix 'JA' confirms the adjustable current limit configuration against the official datasheet. Ensure the ordering part number matches the required package type and tape/reel specifications. Confirm that the AEC-Q100 qualification aligns with the target automotive application requirements before finalizing procurement orders.

Selection Notes

Select this component when an adjustable current limit between 500 mA and 2.1 A is required for high-side switching applications. It is suitable for designs needing controlled turn-on/turn-off speeds to reduce electromagnetic interference. Consider the 6-UDFN package size and the 2.5 V to 5.5 V operating voltage range for compatibility with standard automotive logic levels.

Part Context

This part belongs to the NCP380 series of high-side power switches designed for automotive environments. The series offers various fixed and adjustable current limit options in compact packages. The NCV prefix indicates automotive grade qualification, ensuring reliability under harsh thermal and electrical conditions typical in vehicle electronics.

Replacement Considerations

NCP380HMUAJAATBG is the commercial equivalent of this automotive-grade part. Other NCV380 variants with fixed current limits may serve as substitutes if adjustable limiting is not required. Verify pinout and thermal characteristics match the existing design layout before substitution.

FAQ

How is the current limit threshold determined?

The current limit is adjustable from 500 mA to 2.1 A using an external resistor connected to the current sense pin.

What triggers the status flag output?

The flag output goes low during overcurrent conditions, reverse voltage events, or excessive junction temperature.
