FEATURES
GENERAL DESCRIPTION
Integrated low Rdson nFET switch: typical 29m 4.5A continuous current capability
The AW338XX features an ultra-low 29m (typ.) Rdson nFET load switch. When input

l
Default Over-
Voltage Protection (OVP) threshold AW33801: 5.95V AW33802: 6.2V AW33805: 6.8V AW33809: 9.98V
tia exceeds the OVP threshold, the switch is turned off
very fast to prevent damage to the protected downstream devices. The IN pin is capable of withstanding fault
voltages up to 35VDC.
The default OVP threshold is 5.95V (AW33801),
AW33812: 14V OVP threshold adjustable range: 4V to 20V Input maximum
voltage rating: 35VDC Fast turn-off response: typical 90ns Over-Temperature Protection (OTP)
n 6.2V (AW33802), 6.8V (AW33805), 9.98V
(AW33809) and 14V (AW33812). The OVP
e threshold can be adjusted from 4V to 20V through
external OVLO pin.
Under-
Voltage Lockout (UVLO) 1.245mm × 1.245mm WLCSP-9 package
APPLICATIONS
fid This device features over-temperature protection
that prevents itself from thermal damaging.
The AW338XX is available in a RoHS compliant 9bump 1.245mm × 1.245mm WLCSP.
