INTEGRATED LOAD SWITCH
µ PA1981
N-CHANNEL/P-CHANNEL MOS FET PAIR
FOR LOAD SWITCH
DESCRIPTION
The µ PA1981 is a N-Channel/P-Channel MOS FET pair for compact
power management in portable electronic equipment where 2.5 to 8 V
input and 2.8 A output current capability are needed.
This load switch integrated a small N-Channel MOS FET (Q1), which
drives a large P-Channel MOS FET (Q2) in one tiny package (SC-95).

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.
