Over-Voltage Protection Load Switch
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 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.
Default Over-Voltage Protection (OVP) threshold
AW33801: 5.95V
AW33802: 6.2V
AW33805: 6.8V
AW33809: 9.98V
AW33812: 14V
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.
OVP threshold adjustable range: 4V to 20V
Input maximum voltage rating: 35VDC
Fast turn-off response: typical 90ns
Over-Temperature Protection (OTP)
Under-Voltage Lockout (UVLO)
This device features over-temperature protection
that prevents itself from thermal damaging.
1.245mm × 1.245mm WLCSP-9 package
The AW338XX is available in a RoHS compliant 9-
bump 1.245mm × 1.245mm WLCSP.

Notice for Typical Application Circuits:
1. When the default OVP threshold is used, connect OVLO pin to GND directly or through a 0Ω resistor. OVLO
pin cannot be left floating.
2. If R1 and R2 are used to adjust the OVP threshold, in order to speed up the OVP response, R1 + R2 < 100kΩ
is recommended. It is better to use 1% precision resistors to improve the OVP threshold precision.
3. CIN = 0.1μF is recommended for typical application, larger CIN is also acceptable. The rated voltage of CIN
should be larger than the TVS maximum clamping voltage, if no TVS is applied and only AW338XX is used,
the rated voltage of CIN should be 50V.
4. COUT = 1μF is recommended for typical application, larger COUT is also acceptable. The rated voltage of
COUT should be larger than the OVP threshold. For example, if the OVP threshold is 6.8V, the rated voltage
of COUT should be 10V or higher.

FUNCTIONAL DESCRIPTION
Device Operation
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.
OVP Threshold Adjustment
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
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.
PCB LAYOUT CONSIDERATION
To make fully use of the performance of AW338XX, the guidelines below should be followed.
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.
2. IN pin routing passes through the external TVS firstly, and then connect AW338XX.
3. Red bold paths on figure 4 and 5 are power lines that will flow large current, please route them on PCB as
straight, wide and short as possible.
4. If R1 and R2 are used, route OVLO line on PCB as short as possible to reduce parasitic capacitance.
5. The power trace from USB connector to AW338XX may suffer from ESD event, keep other traces away from
it to minimize possible EMI and ESD coupling.
6. Use rounded corners on the power trace from USB connector to AW338XX to decrease EMI coupling.
