NCP380HMUAJAATBG Description

Short technical summary and product information.

The On Semiconductor NCP380HMUAJAATBG is a single-channel high-side P-channel power switch designed for general-purpose power distribution and load driving applications. It operates over a wide input voltage range of 2.5V to 5.5V, making it suitable for 3V and 5V systems.

 

The device features an adjustable current limit that can be set from 500mA to 2.1A via an external resistor, protecting downstream circuitry from overcurrent conditions. Typical on-resistance is 55mOhm, ensuring efficient power delivery. The switch is slew-rate controlled to minimize inrush current during turn-on, and it includes a status flag output for fault indication.

 

Protection features include adjustable current limiting and undervoltage lockout (UVLO). The device also meets IEC61000-4-2 ESD specifications with 8kV contact and 15kV air discharge immunity, enhancing system robustness.

 

Packaged in a compact 6-UDFN with exposed pad (2x2mm), the NCP380HMUAJAATBG is surface-mount and operates over a junction temperature range of -40°C to 125°C. It is lead-free and RoHS3 compliant (unverified).
