NCP45790IMN24RTWG

Product Overview

The NCP45790IMN24RTWG from onsemi is a high-side N-channel power switch and load driver in the ecoSWITCH™ series, in a 14-DFN (4x4) surface-mount package. It is a 1:1 single-output switch with non-inverting control, operating from a 3 V to 5.5 V supply and switching loads from 3 V to 24 V at up to 8 A. It includes slew-rate-controlled switching and protections: adjustable current limiting, open-load detection, over-temperature, reverse-current, and UVLO.

Key Features

• Single high-side N-channel output with 1:1 ratio and non-inverting control.
• Load voltage 3 V to 24 V; supply 3 V to 5.5 V; max output current 8 A.
• Typical Rds On 5.6 mOhm; slew-rate-controlled switching.
• Protections: adjustable current limiting, open-load detect, over-temperature, reverse current, UVLO.
• 14-DFN (4x4) surface-mount package; 14-VFDFN exposed pad case.
• Operating temperature -40°C to 85°C (TA).

Applications

• Switching loads in systems powered from 3 V to 24 V rails.
• Power gating of modules controlled by 3 V to 5.5 V logic outputs.
• Load control where controlled turn-on and turn-off slew rate reduces abrupt current changes.

Design & Procurement Notes

Designers should confirm that load voltage remains within 3 V to 24 V, supply voltage remains within 3 V to 5.5 V, and output current does not exceed 8 A. The non-inverting input and high-side N-channel output affect control polarity and switching behavior. Slew-rate control and fault protections support predictable load switching, while the 14-DFN (4x4) exposed-pad package and -40°C to 85°C (TA) range should be considered for layout, thermal management, and ambient conditions.
