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
