DESCRIPTION
The
μ
PA1901 is a switching device, which can be driven
directly by a 2.5 V power source.
This device 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.

Remark
The diode connected between the gate and source of the transistor serves as a protector against ESD. When
this device actually used, an additional protection circuit is externally required if a voltage exceeding the rated
voltage may be applied to this device.
