Over-Voltage Protection Load Switch

FEATURES

GENERAL DESCRIPTION



Integrated low R_dsonnFET switch: typical 29m

4.5A continuous current capability

The AW338XX features an ultra-low 29m (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 35V_DC.

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: 35V_DC

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 R₁and R₂are 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. 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 AW338XX is used,

the rated voltage of C_INshould be 50V.

4. 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 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 V_INfalls 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

V_{IN_OVLO}

=

V_{OVLO_TH}

R₂

The adjustment range is 4V to 20V. When the OVLO pin voltage V_OVLOexceeds V_{OVLO_SEL}(0.26V typical), V_OVLO

is compared with the reference voltage V_{OVLO_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 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 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 C_INon the

top layer (same layer as the AW338XX) and close to IN pin, and place the output capacitor C_OUTon 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 R₁and R₂are 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.
