NCP45522IMNTWG-H

Overview

The NCP45522IMNTWG-H is a single-channel load switch from onsemi, designed for power distribution applications. It operates within a supply voltage range of 3 V to 5.5 V and supports an output current of 6 A. The device features a maximum on-resistance of 31.7 mΩ, with a typical turn-on time of 260 µs and turn-off time of 200 ns. It is housed in a compact DFN-8 package (2x2 mm) and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates a high-current single-pole single-throw (SPST) switch for efficient power routing.
• Provides fast switching speeds with controlled rise and fall times to minimize inrush currents.
• Operates over a wide industrial temperature range suitable for harsh environments.

Applications

• Power distribution networks in embedded systems
• Load switching for peripheral devices in consumer electronics
• Battery-powered equipment requiring efficient power management

Procurement Notes

Verify component authenticity through authorized channels due to the presence of counterfeits in the market. Confirm that the specific suffix matches the required specifications, as variations may exist within the product family. Ensure compliance with RoHS directives and check for moisture sensitivity level requirements during storage and handling procedures before assembly.

Selection Notes

Select this component when a single channel with 6 A capacity is required within a 3 V to 5.5 V system. Consider the DFN-8 package for space-constrained designs. Evaluate thermal performance based on the 31.7 mΩ on-resistance and expected load conditions. Compare against other ecoSWITCH™ variants if different current ratings or pin configurations are needed.

Part Context

This part belongs to onsemi's ecoSWITCH™ series of integrated load switches. These devices are engineered to provide robust protection and control for power distribution lines. The NCP45522 variant specifically targets applications needing moderate current handling in a small footprint, complementing higher or lower current options in the same family.

Replacement Considerations

Check for direct substitutes within the NCP4552x series, such as NCP45521 or NCP45524, depending on current and resistance requirements. Verify pin compatibility and electrical parameters before substitution. Note that some variants may have different thermal characteristics or packaging options.
