NCV380LMUAJAATBG

Overview

The NCV380LMUAJAATBG is a high-side power distribution switch featuring an integrated P-channel MOSFET with a typical on-resistance of 55 milliohms. It operates within a load voltage range of 2.5V to 5.5V and supports an adjustable output current limit between 500mA and 2.1A via an external resistor. The device includes controlled slew rates to minimize current ringing during switching events. Protection features include adjustable current limiting, under-voltage lockout (UVLO), and reverse voltage detection. A status flag output indicates fault conditions such as overcurrent or overheating.

Feature Summary

• Integrates a P-channel MOSFET for high-side power distribution with low on-resistance.
• Provides adjustable current limiting from 500mA to 2.1A using an external resistor.
• Includes controlled slew rate management to reduce switching noise and current ringing.
• Features a logic flag output that signals faults including overcurrent, reverse voltage, and thermal issues.

Applications

• Power distribution in portable electronic devices
• Capacitive load switching applications
• Short circuit protection circuits

Procurement Notes

Verify the specific suffix 'JAATBG' against the official datasheet to confirm the package type, temperature grade, and marking details. Ensure the external resistor value matches the desired current limit threshold. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before ordering.

Selection Notes

Select this component when a high-side switch with adjustable current limiting is required for loads up to 2.1A. It is suitable for applications needing reverse voltage protection and thermal fault indication. Compare with fixed-limit variants if external adjustment is not necessary. Ensure the operating temperature range meets system requirements.
