Over-Voltage Protection Load Switch
GENERAL DESCRIPTION
The AW338XX features an ultra-low 29m (typ.)
Rdson nFET load switch. When input voltage
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.

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.
APPLICATIONS
The default OVP threshold is 5.95V (AW33801),
6.2V (AW33802), 6.8V (AW33805), 9.98V
(AW33809) and 14V (AW33812). The OVP
threshold can be adjusted from 4V to 20V through
external OVLO pin.

FUNCTIONAL DESCRIPTION
Device Operation
ti
a
l
If the input voltage is between UVLO and OVP threshold, the internal charge pump begins to work after
debounce time, the gate of the nFET switch will be slowly charged high till the switch is fully on. If the input
voltage exceeds the OVP trip level, the switch will be turned off in about 90ns. If input voltage falls below UVLO
threshold, or over-temperature happens, the switch will also be turned off.
Over-Voltage Protection
If the input voltage exceeds the OVP rising trip level, the switch will be turned off in about 90ns. The switch will
remain off until VIN falls below the OVP falling trip level.
n
OVP Threshold Adjustment
n
fi
d
e
If OVLO pin is not grounded, and by connecting external resistor divider to OVLO pin as shown in the typical
application circuit, between IN and GND, the OVP threshold can be adjusted as following:
R1+R2
VIN_OVLO=
VOVLO_TH
R2
The adjustment range is 4V to 20V. When the OVLO pin voltage VOVLO exceeds VOVLO_SEL(0.26V typical), VOVLO
is compared with the reference voltage VOVLO_TH(1.20V typical for AW33801/AW33805/AW33809/AW33812,
1.23V typical for AW33802) to judge whether input supply is over-voltage. Take AW33801 for example, if we
select R1 = 51kΩ and R2 = 12.4kΩ, then the new OVP threshold calculated from the above formula is 6.14V.
USB On-The-Go (OTG) Operation
C
o
If VIN = 0V and OUT is supplied by OTG voltage, the body diode of the load switch conducts current from OUT
to IN and the voltage drop from OUT to IN is approximately 0.7V. When VIN > VIN_UVLO, internal charge pump
begins to open the load switch after debounce time. After switch is fully on, current is supplied through switch
channel and the voltage drop from OUT to IN is minimum.
ic
PCB LAYOUT CONSIDERATION
To make fully use of the performance of AW338XX, the guidelines below should be followed.
in
1. All the peripherals should be placed as close to the device as possible. Place the input capacitor CIN on the
top layer (same layer as the AW338XX) and close to IN pin, and place the output capacitor COUT on the top layer
(same layer as the AW338XX) and close to OUT pin.
a
w
2. Route the power line (shown in Figure 1) as widely and shortly as possible to reduce parasitic impedance.
