Over-Voltage Protection Load Switch
FEATURES
GENERAL DESCRIPTION
Integrated low Rdson nFET switch: typical 30m
4.5A continuous current capability
The AW332XX features an ultra-low 30m (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 32VDC.
Over-Voltage Protection (OVP) threshold
AW33201: 6.2V
AW33205: 6.8V
AW33209: 10.5V
Input maximum voltage rating: 32VDC
Fast turn-off response: typical 100ns
Over-Temperature Protection (OTP)
Under-Voltage Lockout (UVLO)
The
OVP
threshold
is
6.2V(AW33201),
6.8V(AW33205), 10.5V(AW33209).
This device features over-temperature protection
that prevents itself from thermal damaging.
1.245mm × 1.245mm WLCSP-9 package
The AW332XX is available in a RoHS compliant 9-
bump 1.245mm × 1.245mm WLCSP.

Notice for Typical Application Circuits:
1. 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 AW332XX is used,
the rated voltage of CIN should be 50V.
2. 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 100ns. 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 100ns. The switch will
remain off until VIN falls below the OVP falling trip level.
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 AW332XX, 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 AW332XX) and close to IN pin, and place the output capacitor COUT on the top layer
(same layer as the AW332XX) and close to OUT pin.
2. IN pin routing passes through the external TVS firstly, and then connect AW332XX.
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. The power trace from USB connector to AW332XX may suffer from ESD event, keep other traces away from
it to minimize possible EMI and ESD coupling.
5. Use rounded corners on the power trace from USB connector to AW332XX to decrease EMI coupling.
