Over-Voltage Protection Load Switch

FEATURES

GENERAL DESCRIPTION



Integrated low R_dsonnFET switch: typical 30m

4.5A continuous current capability

The AW332XX features an ultra-low 30m (typ.)

R_dsonnFET 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 32V_DC.

Over-Voltage Protection (OVP) threshold



AW33201: 6.2V

AW33205: 6.8V

AW33209: 10.5V



Input maximum voltage rating: 32V_DC

Fast turn-off response: typical 100ns

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

Notice for Typical Application Circuits:

1. C_IN= 0.1μF is recommended for typical application, larger C_INis also acceptable. The rated voltage of C_IN

should be larger than the TVS maximum clamping voltage, if no TVS is applied and only AW332XX is used,

the rated voltage of C_INshould be 50V.

2. C_OUT= 1μF is recommended for typical application, larger C_OUTis also acceptable. The rated voltage of

C_OUTshould be larger than the OVP threshold. For example, if the OVP threshold is 6.8V, the rated voltage

of C_OUTshould 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 V_INfalls below the OVP falling trip level.

USB On-The-Go (OTG) Operation

If V_IN= 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 V_IN> V_{IN_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 C_INon the

top layer (same layer as the AW332XX) and close to IN pin, and place the output capacitor C_OUTon 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.
