DESCRIPTION
The µPA1890 is a switching device which can be driven directly by a 4.0-V power source.
The µPA1890 features a low on-state resistance and excellent switching characteristics, and is suitable for applications such as power switch of portable machine and so on.

FEATURES
• Can be driven by a 4.0-V power source
• Low on-state resistance
